It’s all over now, baby blue:
Longtime Republican congressman Mike Castle has ruled out a write-in campaign in the U.S. Senate race in Delaware.
Castle is also a former two-term governor and the longest serving congressman in state history. He lost the GOP primary earlier this month in a stunning upset to tea party favorite Christine O’Donnell.
He issued a statement Wednesday night saying he had ruled out a write-in campaign, which many supporters had asked him to consider.
Still, of course, no O’Donnell endorsement.
