Frank LoBiondo, a 12-term Republican representing New Jersey's 2nd Congressional District, announced his retirement Tuesday. Politico notes that "the decision will open up a battleground district in southern New Jersey that LoBiondo has held easily since 1994. New Jersey's 2nd District backed President Donald Trump with 50.6 percent of the vote to Hillary Clinton's 46 percent in 2016. But former President Barack Obama also won the seat twice with between 53 and 54 percent of the vote."
Sabato's Crystal Ball has changed the rating of the district from 'Safe Republican' to 'Toss-up'.
32 House members, including 22 Republicans have announced plans to retire and/or seek another elected office in 2018. That list may grow shortly: It was also reported Tuesday that Arizona House Republican Martha McSally will challenge Kelli Ward for the Republican nomination in the 2018 U.S. Senate race there. This is the seat being vacated by incumbent Republican Jeff Flake. No official announcement has been made yet.
