Via Political Wire, a NYT op-ed offers up the one Kerry running mate none of us thought of that would guarantee a win for Kerry – Bill Clinton:

The Constitution does not prevent Mr. Clinton from running for vice president. The 22nd Amendment, which became effective in 1951, begins: "No person shall be elected to the office of the president more than twice."

...

In exchange for joining the ticket, Mr. Clinton could negotiate for plum assignments as vice president. Mideast peace? National health care? Racial equality? He could focus on any or all of them. And from a purely personal standpoint, it might be especially gratifying for Mr. Clinton to be part of the team that defeats the man who four years ago promised to restore "character" to Mr. Clinton's own White House.

Somehow, I think the Supreme Court would find a way to prevent this from happening. Ah, but we can dream, can't we?

Edwards would make the best running mate for Kerry right now. Southern charm, big smile, populist message. And more name recognition than Bill Richardson. Or Evan Bayh. I'm not sure how you even pronounce "Bayh."
