Republican Rep. Susan Brooks of Indiana's 5th congressional district will not seek a fifth term in 2020. Absent an incumbent, The Cook Political Report and other forecasters have moved this suburban Indianapolis district from 'safe' to a consensus rating of 'lean Republican'. The district has demographic similarities to other affluent districts that have been trending away from the GOP during the Trump era. That said, the president won the district by 12 points over Hillary Clinton in 2016 and will, of course, be seeking a 2nd term in 2020.
Brooks is the 8th current member of the U.S. House to announce a 2020 departure. Five are retiring, while two are running for Senate. Montana's at-large GOP Rep. Greg Gianforte recently announced he would be running for governor.
