Since President Donald Trump took office in January 2017, nearly 40 percent of Republican lawmakers have either left or plan to do so, including those who have retired as well as those who have lost re-election.

Rep. Paul Mitchell (R-MI), a two-term congressman who surprised Washington with his retirement announcement days after Trump tweeted that four congresswomen of color should “go back” to their countries of origin, told The Washington Post this month that he didn’t sign up for the “petty, childish b------t” that goes along with the Trump presidency.

“Did any member of this conference expect that their job would start out every morning trying to go through the list of what’s happening in tweets of the day?” Mitchell asked, referencing the president's tweets. “We’re not moving forward right now. We are simply thrashing around.”

Mitchell is just one of “41 House Republicans have left national politics or announced they won’t seek reelection in the nearly three years since Trump took office,” The Post reported, noting that in former President Barack Obama’s first term, just 25 Democrats retired.

And the reason for the exodus could not be more clear, even if Republicans are unwilling to admit their true motives in public. While most cite family as the reason for their departures, The Post reported that in private, Republicans are displeased with the party’s direction under Trump.
