Indeed. You can't make up 21 points in four months when your state HATES you. Even if this year is a big republican wave, this will be a bright spot on the map for the democrats. The best Corbett can hope for at this point is to bring it within 10 points, and even that will be tough, which is why I recently moved this to Safe D. *glares at cook political report, who still has this at Toss-Up*
