What are they putting in Joe Scarborough's "Morning Joe"?

He was acting awful loopy during this interview with John Edwards yesterday... Good thing Mika Brzezinski was there to nervously laugh off his line about Republicans. Maybe it was truth serum. If only Fox News used the same catering people.

BRZEZINSKI: What do you make of what's going on in the Republican Party, with the surge of Governor Huckabee?

And some analysts might say that the Republicans don't know what they want yet, but Huckabee seems to be sticking, at least for now, and is winning heavily in several states...

(RAUCOUS LAUGHTER FROM SCARBOROUGH)

BRZEZINSKI: What?

SCARBOROUGH: Republicans never know what they want.

BRZEZINSKI: Well...

SCARBOROUGH: Other than war. We want war.

BRZEZINSKI: Oh, (OFF-MIKE) Don't listen to him.

(LAUGHTER)

What do you make of Governor Huckabee's surge so far?

What do you think voters are responding to here?

EDWARDS: Oh, I have to be honest. I don't spend a lot of time following what's happening on the Republican side...

(LAUGHTER)

BRZEZINSKI: That's smart.
