Bob Kerrey changes mind, will run for Senate again

His return would give Democrats new hope in a race that would likely be lost if he doesn’t run. The Democratic bench in Nebraska is very thin behind retiring Sen. Ben Nelson (D-Neb.) and Kerrey.

Kerrey, of course, will have to overcome charges of carpetbagging. Despite being a former governor and senator from Nebraska, he moved to New York after retiring from the Senate in 2001 and even flirted with running for mayor of New York City.
