Crossover voting is going to be DISASTEROUS in 2012 because Obama will be running, so ALL the Democrats will Crossover and vote for the WEAKEST REPUBLICAN!! THIS MUST STOP!!
I agree that it will hurt, BUT, you can’t stop it in states that don’t require party registrations. The truth is, if anyone can register as anything they wish, it’s just as easy to cross over.
What we really need to do is get rid of “winner-take-all” in the state primary voting.
