In the 2008 election, Mike Ferguson (who had first been elected in 2000, replacing Bob Franks) did not seek another term. Linda Stender won the Democratic nomination unopposed, while Republican primary voters chose State Senator Leonard Lance in a field of eight candidates. In the 2008 general election, Lance defeated Assemblywoman Linda Stender by a margin of 25,833 votes and became the Congressman.
In the 2010 general election, Democratic challenger Ed Potosnak challenged Lance, but Lance defeated Potosnak by a margin of 59% to 41%. For the 2012 election, both Potosnak and former Edison Mayor Jun Choi have announced their candidacies for the Democratic nomination, although the field could be affected by Congressional redistricting which will take place prior to the election.
