Independent congressman Justin Amash is forming an exploratory committee to run for the Libertarian nomination for President, he announced late on Tuesday.

Amash refused to rule out a third-party run for President had left the Republican Party over what he called excessive partisanship last summer. His latest announcement signals that the Michigan congressman has now jumped into the 2020 presidential race.

“Let’s do this,” he wrote on social media, alongside a link to a presidential campaign website.

“Today, I launched an exploratory committee to seek the [Libertarian Party]’s nomination for president of the United States,” Amash continued. “Americans are ready for practical approaches based in humility and trust of the people.”

The campaign website includes just one short paragraph, pitching Amash as both an ideologue committed to the Libertarian demand for limited government, and a civility-minded alternative to partisan politics.

“For something new. For a government that secures our rights. For equality before the law. For an end to cronyism. For a government that fulfills its purpose and recognizes its limits,” the paragraph reads. “For practical approaches based in humility and trust of the people. For an honest, principled president who will defend the Constitution and put individuals first.”

Amash has emphasized his appeal to Americans tired of “partisan discord,” emphasizing his odd-man-out status as the only Independent in the House of Representatives.

Several Democrats had pushed for Amash to serve as impeachment manager in the trial of President Donald Trump earlier this year, hoping that his stature as a non-partisan voice would help lend an air of neutrality to the proceedings.

Amash has now chosen to align himself with a party, albeit one that is both underdog and outsider. The Libertarian Party is now on the presidential ballot in thirty-five out of fifty states, and will have to fight for ballot access in the remaining fifteen states.

The presidential primary season has mostly passed for all major parties, but Libertarian primaries are non-binding. Delegates are free to choose any candidate at the party convention in Austin, Texas in spite of the primary election results.

The convention was initially planned for next month, although Libertarian leadership has signalled that it may be postponed due to the coronavirus pandemic.

Amash is not the first former Republican to aim for the Libertarian nomination in 2020.

Lincoln Chafee, who served as a Republican senator, an Independent governor, and a Democratic, jumped into the Libertarian race two months before the Super Tuesday primaries. He similarly campaigned on his bipartisan credentials and national political profile.

But Chafee’s campaign ended abruptly earlier this month. He announced that he was dropping out of the race on April 5 without endorsing another candidate.

Amash, however, indicated that he sees a path to success.

“We’re ready for a presidency that will restore respect for our Constitution and bring people together,” he wrote on Wednesday night. “I’m excited and honored to be taking these first steps toward serving Americans of every background as president.”
