Michigan Rep. Justin Amash bailed out of the race for the White House Saturday, citing a long list of reasons for abandoning his bid to become the Libertarian Party’s standard-bearer.

“I’ve concluded that circumstances don’t lend themselves to my success as a candidate for president this year,” Amash said in a string of tweets that cited political polarization, social distancing, online voting, fund-raising trouble and more as reasons to drop his presidential hopes.

Amash, who left the Republican Party last year, has been a fierce critic of President Trump. He was the only non-Democrat in the House to vote for Trump’s impeachment in December.

Trump mocked Amash’s potential White House run when the congressman launched an exploratory committee last month.

“No, I think Amash would make a wonderful candidate,” Trump tweeted April 29. “Especially since he is way behind in his district and has no chance of maintaining his Congressional seat.”

“I like him even more than Jill Stein!” he wrote — referring to the Green Party candidate who siphoned votes away from Hillary Clinton in 2016.
