If the GOP doesn’t restrict primary voting the left can game the system. They did it with McCain, and will do it again if the opportunity presents itself.
Romney won't run, because he knows he cannot and will not win. Romney would never, could not ever become President.
Jindal/Palin is the Team to beat. And, hopefully, they'll be other great Conservatives in the mix to mix it up!
Whether or not liberals will game the system going forward is a good thing to debate. They might try it in 2012 when they already know that Obama will be their nominee. With their nominee locked up, they might try to do an "Operation Chaos" of their own.
They will mess up our primaries again.
