So I don't think that obviously Toomey is not going to have a choice and I expect it's going to be Sestak at the end of the day, because Arlen Specter is clearly out there, you know, in the middle of the road with yellow stripes and dead armadillos, as they say.
TAPPER: Glenn, you see this, and specifically President Obama's endorsement of Arlen Specter, as a larger institutional problem in Washington.
GREENWALD: Well, Washington basically exists to perpetuate the power of incumbents. And so it's extraordinary to watch. Arlen Specter, who was a Republican, and a fairly loyal and devoted Republican. He helped the Bush agenda in all sorts of ways, be supported by the White House. People who gave money to the Democratic apparatus are having that money diverted or directed to someone who spent their life in the Republican Party and to try to defeat an actual Democrat a real progressive. And that's what Washington does. It perpetuates the power of incumbency, and that's why the American people are so largely cynical about what takes place in the city.
TAPPER: Arlen Specter is not the only one facing a tough Tuesday. In Kentucky, the secretary of state, Trey Grayson, is facing a challenge from Rand Paul. He is the son of Congressman Ron Paul, and even though it is an open seat, Grayson is the secretary of state, so he's seen as the establishment candidate.
Here's the campaign ad he is running against Rand Paul, who is a Tea Party candidate.

(UNKNOWN): We live in dangerous times.
But not in Rand's world. Rand wants to decriminalize dangerous drugs. Rand Paul even questions whether Afghanistan poses a threat to the U.S., and supports an immediate withdrawal from Iraq.
Rand's world. Wild, wacky and dangerous.
(END VIDEO CLIP)
TAPPER: George, if Rand Paul wins on Tuesday, I would think, if I were the Democratic candidate, I would just run Trey Grayson's ads. But can Rand Paul win?
WILL: Sure. I mean, look, there's a question as to whether or not they know how to poll in Republican primaries in Kentucky, because they haven't had that many hotly contested ones. The polls are 15 points apart at this point. But it seems to me --
TAPPER: With Grayson?
WILL: Grayson has polls that he says that show him tied. And it's McConnell's poll taker who has been doing these things.
TAPPER: McConnell has endorsed Grayson.
WILL: And the voters will sort this out. But you know, it seems to me when Ron Paul -- Rand Paul says, it's not clear that Afghanistan is crucial to our security, a lot of people in Kentucky probably say, that's not crazy, that's a sensible view.
TAPPER: Do you think this is an example of the Tea Partiers flexing their muscles yet again? What's going to happen, do you think?
CRAIG: Well, it's not my party, and I haven't been following as closely as your other guests here. But it seems to me a repeat of what happened in Nevada with Senator Bennett.
CRAIG: I mean, sorry, Utah, with Senator Bennett, a long- standing incumbent who is thrown out in the Republican convention.
TAPPER: Is that how you see it, Helene?
