Dennis Flynn is already getting people to not think Rep or Dem. He endorses and will voting for Ron Paul for president. His campaign manager is a Republican. He's sending a clear message that it's about principle over party.
The 10th District of NJ is an 80% Democrat voting district. Dennis Flynn's five opponents all support the president's interventionist foreign policy, attack on civil rights, and marriage with crony corporatism. Getting Democrats to wake up and vote for someone speaking against these things is more important that the letter next to his or her name.
