Forbes still lives in the 4th District, but that does not pose a legal impediment to running in the 2nd District. Rep. H. Morgan Griffith, R-9th, lived just outside the district when he first ran to represent it in 2010.

In the new congressional map, Rigell’s 2nd District loses some Newport News precincts and picks up the city of Williamsburg, York County and part of James City County.

The spike in voter turnout in a presidential year could give Democrats a chance to pick up the seat, as Glenn Nye did when he was swept into office during the 2008 election of President Barack Obama.

Rigell defeated Nye in 2010, then won re-election in 2012 and 2014.

The new map makes the 2nd District “very slightly more Republican,” Sabato said.

Rigell said he will keep a pledge he made when he first ran in 2009 and will refuse all retirement benefits for which he qualifies as a result of his service in Congress.
