Bill Hughes Jr., the son of former Rep. Bill Hughes, has announced that
he will run against Frank LoBiondo in 2014. State Sen. Jeff Van Drew was also considering a run against LoBiondo, though he would have to resign in order to run.
I don't think LoBiondo will loose, but he hasn't had a serious race in a long while and his fundraising hasn't been high so retirement is clearly a possibility.
Jon Runyan also has a likely opponent in Burlington County Freeholder Aimee Belgard, who is
reportedly in talks with the DCCC. Freeholder is New Jersey's equivalent of County Commissioner, and Burlington County is 60% of the population of NJ-03.
Both Runyan and LoBiondo are in districts Obama won in 2012.
