Deleware Upset?

If the election were today, probably. As of today, a poll is out showing Christine O'Donnell ahead of the establishment backed Mike Castle. She is leading 47 to 44, and while that is just outside the margin of error, it is enough to give many a pause. In one month, Mike Castle went from 60 percent favorability to 43. Why? Because in one month, he was constantly attacked as being too liberal, and he has not fought back. There is still four days for things to change, however, I do not think that this will be the case. Even if Mr. Castle, who is seen as a moderate, were to go on offense, it might not be enough to save him. His only hope is if Ms. O'Donnell loses support among conservatives. And really, how likely is it?
