GOP Rep. Phil Roe of Tennessee announced Friday that he will retire at the end of the current Congress. Roe is in his 6th term, and represents the most conservative district in this deep red state.  Donald Trump won here by about 57% over Hillary Clinton in 2016; only five districts across the country had larger Trump margins that year¹.

36 current members of the House have announced they will not run in 2020: 27 Republicans and 9 Democrats.  The number includes Rep. Duncan Hunter (R, CA-50), who is expected to leave Congress early this year.

_{¹ Interestingly, three of the six incumbents in these reddest of districts are retiring. In addition to Roe, that includes Reps. Michael Conaway (TX-11) and Mac Thornberry (TX-13)}
