It doesn't matter whether the Republican nominee is Mitt Romney or Newt Gingrich (or Ron Paul or Rick Santorum or Joe the Plumber).
Republican leaders will do everything in their power to get their voters out to vote on election day 2012. And they will succeed because the Republican base in nearly insane and absolutely unanimous in their opposition to Barack Obama. They will crawl on hands and knees to their polling places, they will drag themselves over dead bodies to vote him out of the White House in 2012.
Simply stated, our obligation if we want to hold onto the White House is to get out and vote and get our like minded friends and family members out to vote.
If you don't show up on election day, you lose the right to bitch and moan about the outcome.
