Delaware: The Return of Christine O'Donnell?

In 2010, Christine O'Donnell famously defeated then-Rep. Mike Castle, R-Del., in the GOP Senate primary — then lost the general election to now-Sen. Chris Coons, a Democrat. (See "I'm not a witch... I'm you.")

Her candidacy serves as a symbol of that cycle, in which three tea-party-backed GOP nominees lost otherwise winnable races to Democrats in Delaware, Nevada and Colorado.

O'Donnell is taking care of her family and will make a decision later about possibly running against Coons again in 2014, Abby Livingston reports in the Farm Team column, Roll Call's weekly state-by-state look at up-and-coming candidates.

Would O’Donnell, who became the bane of national Republicans that cycle, run again? Her former campaign manager, Matthew Moran, said it’s a possibility.

“We hear from Christine’s supporters everyday that they want her to run again,” he wrote in an email to CQ Roll Call. “However, both of her parents faced serious illness this past year so she won’t be making a decision about 2014 until they are in the clear.”
