Describing himself as "hurt and stunned" by his Delaware U.S. Senate primary defeat to Christine O'Donnell (R), Rep. Mike Castle (R) told the Wilmington News Journal he isn't ruling out the possibility of a write-in campaign.
While Castle said he "probably" would not run, but has not ruled it out "simply because it's there, simply because I've had a number of people who've asked that I do that."
He has until the end of the month to declare his intentions.
