Bob Kerrey's next race

After promising not to make us wait for a decision, he made us wait for a decision. Kerrey will not be running for Senator of Nebraska. My guess is he saw a real challenge ahead and hated the prospect of ending his political career on a sour note. He doesn't sound like a guy who is finished, though. I suspect he is eyeing Hillary's Senate seat. NY is an easier place for him to win. He's certainly lived there longer than Hillary did, and if he gets the Dem nod, who is on the Republican bench?
