The Democratic nominee in Maryland's 1st Congressional District, Wendy Rosen, has dropped out of the race, according to multiple media reports. The Salisbury Daily Times reported that Rosen sent a letter to state Democratic Party chairwoman Yvette Lewis announcing her resignation and saying "personal issues have made this the hardest decision that I have had to make."
Earlier in the day, Lewis had called for her resignation and said in a statement that "allegations of electoral law violations were brought" to the party's attention. Lewis sent a letter to the state attorney general earlier Monday saying the party had found evidence that Rosen registered and voted in both Maryland and Florida in the 2006 general election and the 2008 presidential primary.
After redistricting, the 1st District became a safer Republican seat, and freshman GOP Rep. Andy Harris was likely to win reelection anyway. The Maryland Democratic Party will get to nominate a new candidate for the district, but it likely won't matter much.
