Sen. Tom Udall won't seek re-election in 2020

Sen. Tom Udall (D-N.M.) announced Monday that he won't seek re-election in 2020 after two terms in office, saying he hopes to "get so much more done to help reverse the damage done to our planet, end the scourge of war, and to stop [President Trump's] assault on our democracy and our communities."

The state of play: Udall's retirement comes at a "pretty ideal" moment for the Democratic Party, tweets the Washington Post's Dave Weigel, who notes that Democrats' success in the state over the last few election cycles means the race "starts as a likely D hold."
