Political analyst Charles Krauthammer says the election next week is really quite simple for Republicans. Win, or consider leaving the country. "This really is a Republican tide," Krauthammer said. "I think the chances are very good, maybe 70%, that Republicans retake the Senate and for good reason. The reason is this is essentially a referendum on Obama. In 2010, it was a referendum on his ideology -- the overreach with ObamaCare, the stimulus, cap and trade -- and now, six years in, it's referendum on ideology, but now added on to that, it's on shear competence." He concluded, "If the GOP can't win back the Senate in a climate like this, maybe the party ought to look for another country."
