The WashPost names Shelley Moore Capito -- whose will-she/won't-she we covered back in the summer -- one of the five biggest (non) candidates who should be kicking themselves as this election comes to a close. (Number one is Delaware's Beau Biden, who would have been running against Christine O'Donnell for Senate.)

Here's their bit on the WVa congresswoman:

2. West Virginia Republican Rep. Shelley Moore Capito: Capito, the lone Republican in West Virginia's House delegation since she was first elected in 2000, was recruited in 2006 to run against then-Sen. Robert Byrd (D-W.Va.); she ultimately decided against it. Four years later, when Byrd's death in July set off a race to succeed him, Capito was again at the top of West Virginia Republicans' lists; again, she demurred, faced with the likelihood of a tough race against popular Gov. Joe Manchin (D). Now, due in part to the deep unpopularity of President Obama and national Democrats in the Mountain State, polls show Manchin facing a tougher-than-expected race against wealthy businessman John Raese (R). The seat is up again in 2012, but the environment may not be as favorable for Republicans as it is at present.
