Update 7:50 PM: Chris Proclaims Polls Closed 1/2 Hour Early! See foot.
The problem with Chris Matthews playing footsie with the idea of running for US Senator from Pennsylvania: when he says something nowadays, how can you tell whether he means it, or is just trying to position himself for a possible run?
Take this evening's Hardball, during which Matthews castigated Joe Lieberman as having been a "terrible" running-mate for Al Gore in 2000. Kiki McLean, a senior Clinton advisor, was Chris's guest. McLean mentioned that she had been an aide to Lieberman in 2000, and to Gore when he was the Veep candidate [1992?]. That set Matthews off.
