When will New Jersey become competitive?

To say any state will stay the way it is forever is foolish.

Basically this. I expect every state (i.e. not DC) to vote for more than one party at least once in the next century. It easily happened during the last century and I don't think we've reached some kind of political stasis right now, although we probably won't see quite the fluidity as we have.
