More likely the Dick Nixon.
The whigs split over slavery. The only issue in our time on that level is abortion. The problem with the parties today isn't over the abortion issue, but one rich jagoff who wants to be president.
The GOP and Democrats will survive just as it has since 1856. It's our job to get off our butts and do more than complain on a message board until it's election year, and make sure we have good people and good organizations in the GOP. It's our only chance. We all need to run for precinct delegate/captain in your area and get involved. We all need to join our local tea parties.
The problem is that most people have no patience for long term fights, little knowledge of party apparatus and logistics, and little activity at the local level. I'm not necessarily pointing the finger at you. I said "we", not you.
On the same note, there's more elections than just president as well. Tim Walberg is a good guy. He's my congressman. Just because Romney sucks doesn't mean I should leave Walberg out to dry. That's what happened with McCain, and I got one term of Marky Mark Schauer. Schauer voted for Cap and Trade and Obamacare. Tim's back thanks to 2010 and will need my help again.
