. . . how can he hope to govern after running such a campaign?
Should the Democrat prevail, he is likely to face a Republican House, if not a Republican — at least a more Republican & more conservative — Senate. Not to mention all those Democratic Senators from “red” states whose seats will be up in 2014 and will be wary of running for reelection with an unpopular incumbent from their party in the White House.
You may say that if he wins, he won’t be unpopular, but the point of this post is that should he win, he will have done so by demonizing his opponent rather than improving his public image. His negatives will remain high, his approval low.
