WASHINGTON – Rep. Justin Amash's announcement that he is leaving the Republican Party makes him a small group of congressmen who have interrupted a party or changed feasts in recent history.

In a Washington Post document published on July 4, Amash said that modern politics was "caught in a partisan death spiral" and announced that his resignation from the GOP would become independent. Amash is the only Republican member of the Congress who has declared his support for suppressing President Donald Trump.

After Amash's statement on his political independence, Trump knocked out Michigan lawmaker and called him "one of the stupidest and most disloyal" in the congress.

Changes in party affiliation are not unusual in American politics. Hillary Clinton volunteered to volunteer for Republican Barry Goldwater's president in 1964 and was active in Republican politics as a young republican before becoming a Democrat. Teddy Roosevelt made sense to President again in 1912 as a representative of the Bull Moose Party instead of running again as Republican.

However, Amash's decision to change lots while in the office is unique.

"Amash is the first Republican house member for 20 years to leave the GOP," explained Antoine Yoshinaka, a state science professor at New York State University in Buffalo and the author of a 2015 book shift.

Only three senators have changed parties while in office in the 21st century, according to Senate data. A US TODAY analysis of the congressional biographical data shows that only five members of the House of Representatives have changed festivals during the 21st century. After changing parties, most of the incumbent companies continue to lose their choice or retire from the office.

Amash is only the third Republican to leave the 21st century party

Only two other Republican members of Congress have left the party since 2000. In 2001, Jim Jeffords of Vermont left the Republican party over what he saw as a right-wing movement on the party's platform and said in a speech at the time that "I've changed my party label but I haven't changed my beliefs. "Jeffords, like Amash, became an independent, although Jeffords caucused with the Democrats.

In 2009, Sen. Arlen Specter of Pennsylvania the Republican Party to become a Democrat. He lost his bid for re-election in 2010 to Sen. Pat Toomey, who originally challenged Specter in the Republican primary.

Change with Political Winds

Most of the members of the Board of Representatives to switch parties while in the office of the past century were sewing democrats who became Republicans when the political winners changed and the south became roots. Parker Griffith, a member of the Alabama Congress, switched from the Democratic Party to the Republican Party in December 2009 in the midst of the Affordable Care Act, also known as Obamacare. Griffith continued to lose the Republican primary to Mo Brooks.

"Amash is the first Republican house member for 20 years to leave the GOP," Yoshinaka said, noting that the last Republican member of Parliament left the party, was New York Congressman Michael Forbes, who switched from the Republican Party to The Democratic Party in 1999 and lost in 2000 Democratic Primary.

Some members have changed lots several times

Rep. Virgil Goode, Virginia, was re-elected in 2000 after switching from being a Democrat to an Independent and in 2002 when he switched to becoming a Republican. At the time of his first switch, he had said he wanted to be able to vote in accordance with his principles without pressure from a political party.

"You don't have any Democrats telling you, didn't vote with the national party line enough," he said in January 2000, according to the Washington Post. "I will vote as I have been in the past."

Goode lost re-election in 2008 to a democrat, Tom Perriello.

The future of Amash in Parliament is unclear

The House of the Republican Conference rules are unclear on the question of what happens if a member of Congress leaves the party.

According to the rules, "All Republican Members of the House of Representatives … and other Members of Parliament as determined by the Republican Representatives Conference … shall be members of the Conference." [19659005] A 2/3 vote of the entire Republican conference, or about 132 out of the 198 members of the conference, would be required to expel a member.

In addition, Amash cannot be removed from his seat on the powerful House Monitoring Committee without a decision of the full House of Representatives to do so, which would require some Democrats to vote for the resolution.

However, Amash's election future is more uncertain. The Detroit Free Press noted that a large roster of Republicans had lined up to run against him in the Republican primary, and now that Amash has left the Republican party, the race for his district becomes a three-way competition between the Republicans, Amash and the Democrats.

However, party change is not always the end of a political career.

Sen. Richard Shelby, R-Ala., Who is currently relying on the powerful Senate Grant, was actually first elected as a Democrat in 1986 and changed to Republican Party in 1994. He has won every election since then.
