President Trump's defeat in his border-wall standoff with Congress has clouded his already perilous path to a second term in 2020, undercutting Mr. Trump's cherished image as a forceful leader and deft negotiator, and emboldening alike his Democratic Challenges and Republican dissenters who hope to block his re-election.
numbers even among Republicans and stirring concern among party leaders about his ability to navigate the next two years of divided government. Mr. Trump, close associates acknowledgment, appears without a plan for mounting a strong campaign in 2020, or for persuading the majority of Americans who view him negatively to give him another chance.
Mr. Trump still commands the loyalty of a passionate electoral base that has rallied to him in trying moments, and advisers believe he will have room to right himself while Democratic presidential candidates are mired in a long nomination fight. Yet they are also growing anxious that he could face a draining primary of his own next year.
Several prominent Trump antagonists are also urging other Republicans to take on the president, and a popular governor, Larry Hogan of Maryland, has indicated
In a sign of the White House's determination to project party unity, a top Trump campaign official, Bill Stepien, traveled to the Republican National Committee meeting in New Mexico this week to orchestrate an ornamental resolution of support for the president. It passed unanimously on Friday afternoon, hailing Mr. Trump for his "effective presidency" even as his shutdown strategy collapsed.
David Winston, a Republican pollster, said the burden was now on Mr. Trump to restore his stature as a leader at forging some of the border-security deal with Democrats, and to deliver a stronger message on the economy.
"Leadership means results," Mr. Winston said. “When you have a shutdown, people look at it, basically, as: the political system has failed.”
Mr. Winston said polling data had been a problematic fight to pick. "Immigration is an important issue," he said, "but people are waking up every day trying to figure out how they are going to pay a set of bills in front of them."
For now, Mr. Trump remains wholly focused on appeasing his conservative base, including perhaps a third of the electorate, despite private G.O.P. polling suggesting that his agenda on immigration has failed to move the country in his favor, Republicans who work closely with the president said.
But Mr. Trump emerged from the shutdown with nothing to show for, having regretted swing voters with his intransigence, while disappointing hard-line supporters at failing to secure any funding for a border wall.

Conservatives still believe that Mr. Trump cannot afford to abandon his crusade for a barrier. Not long before Mr. Trump agreed to reopen the government, Representative Mark Meadows of North Carolina, a White House ally who leads the hard-line Freedom Caucus, arguing that the wall fight was vital to the president's re-election hopes.
"It's not lost on any of us that a central component of what he said when he ran in 2016 has to be addressed in a meaningful way, ”he said in a recent interview.
Privately, some of Mr. Trumps 2016 aides have said they are pessimistic about his path to 270 electoral votes after his party's term defeats in states like Michigan, Pennsylvania and Wisconsin. An Associated Press on Wednesday showed that Mr. Trump's overall approval rating had dropped to 34 percent, with his support among Republicans dipping below 80 percent – a starting turn for a president who strives for total control of the GOP, and has usually achieved it.
The Mueller investigation looms as another destabilizing force for the president. David Kochel, a Republican strategist based in Iowa who is opposed to Mr. Trump said the special counsel's eventual report could determine whether Mr. Trump is vulnerable in primary.
"That will be a focusing mechanism for the party," Mr. Kochel said.
While core Republican voters remain loyal to him and is not currently facing a contest for the nomination, Mr. Trumps low standing with political moderates and especially women is leading some G.O.P. "I think it is healthy and appropriate for the party to consider in 2020 whether this is really the path it wants to continue taking," said David F. Holt, the Republican mayor of Oklahoma City, where a Democrat won a stunning house last year thanks in part to the suburban antipathy toward Mr. Trump.
The 2020 election is nearly two years away and Mr. Trump has time to build a political operation, marshal support from financial backers and make his case to the American people. Mr. Trump captured the presidency with a largely improvisational candidacy, guided by his own instincts for personal combat and cultural division, and the strategic discipline of most presidential campaigns.

Mr. Trump is especially fixated on two well-known Democrats, speaking frequently about Joseph R. Biden Jr., the forms vice president of which Mr. Trump regards as his most dangerous potential opponent, and Senator Elizabeth Warren of Massachusetts. Some of his advisers are more preoccupied with two other challengers, who would offer a stronger generational contrast with the 72-year-old president: Senator Kamala Harris of California and Beto O'Rourke, the former Texas Senate candidate.  In this volatile moment, however, Mr. Trump and his aides have just been focused on heading off competition from fellow Republicans. In addition to direct resolution of support from the R.N.C. – Mr. Trump tweeted approvingly Saturday morning, suggesting re-election "should be easy" "- Mr. Stepien, the former White House political director, has been leading an effort to ensure there is no insurrection at next year's convention in Charlotte, N.C.
Now a top aide on Mr. Trump's campaign, Mr. Stepien and his deputies have been consulting party leaders about shutting off avenues to a challenge and ensuring that states cannot put forward "favorite son" candidates to contest the president's renomination.
Mr. Trump also has a team of aides to guarantee that only political loyalists are elected to serve as delegates to the convention. To that end, Mr. Stepien sent some of his staff members this month to see that their preferred candidate was in charge of the Maine Republican Party.
The fruit of some of those efforts were on display at the R.N.C. meeting outside Albuquerque, where enthusiasm for Mr. Trump was undimmed at least publicly. The party leaders ignored Mr. Stone's arrest, which took place just hours before they gathered, and Ronna McDaniel, the party chair, did not devote from her prepared remarks, to the "manufactured scandals".
Jeff Kent, the party committeeman from Washington State "May America Great Again" has been named as officials.
"To the press in the back of the room," said Mr. Kent, his voice rising, "Please tell the world we will always wear this hat and we will always support our great president, Donald A. Trump." (The president's middle initial is "J.")
Other Republican view Mr. Trump's political stumbles as an opportunity to lure a challenger into the race, with Mr. Hogan emerging as a new subject of their efforts. At a December conference hosted by the Niskanen Center, a right-of-center think tank, Mr. Hogan spoke briefly with William Kristol, an implacable Trump critic in the conservative press, who argued that the president was widely understood, people briefed on the conversation said. Hogan, 62, is set to meet more formally in the coming weeks with Mr. Kristol and Sarah Longwell, a Republican strategist helping marshal opposition to Mr. Trump. Mr. Kristol and Ms. Longwell have been meeting with Republican donors and potential challengers, sharing focus group and polling data about the president's vulnerability with what they call "Reluctant Trump Voters," according to a copy of their presentation by The New York Times.
. Hogan is planning a trip to Iowa in his capacity as an officer of the National Governors Association. But his advisers also recently reached out to Mr. Kochel, the Iowa-based strategist, to ask that he has a dinner with similarly minded Republicans while Mr. Hogan is there, according to an associate of Mr. Kochel briefed on the exchange
Jerry Taylor, president of the Niskanen Center, said Mr. Hogan had “made it clear that the door is open to a potential candidacy, but no decision has been made.”
In addition to Mr. Hogan, William F. Weld, the former Republican governor of Massachusetts, is a challenge to Mr. Trump as a small-government moderate, people who have spoken to him said. Mr. Weld, 73, who was the Libertarian Party's vice-presidential nominee in 2016, has discussed either opposing Mr. Trump in the Republican primaries or seeking the Libertarian presidential nomination.
Mr. Weld declined to comment on his deliberations, and Mr. Hogan declined through an aide to be interviewed.
Other Republicans known to be entertaining campaigns against Mr. Trump include John R. Kasich, the former governor of Ohio, who ran in 2016; Senator Ben Sasse of Nebraska; and Jeff Flake, the former senator from Arizona. But Mr. Sasse is said to have grown uneasy about the idea and Mr. Kasich and Mr. Television by Bruce Berke, a Republican Strategist in New Hampshire. Kasich, said he currently saw Mr. Trump as unassailable in a G.O.P. primary.
“A primary challenge in 2020, as of today, would be futile for anyone,” Mr. Berke said.
Still, Republican donors will know just how damaged the president may be at the end of this year before they truly commit to a challenge.
Asked if he would be willing to raise money for a primary opponent of Mr. Trump, Stanley Druckenmiller, a New York-based investor who has given millions to Republican candidates, said, "If I thought a candidate would be a good president and had a realistic chance of securing the nomination, yes, of course." 19659040]
