Commenting on a new joint interview with John McCain and Sarah Palin, NBC News Political Director Chuck Todd described the Republican ticket as lacking cohesion, chemistry, and (he hinted) trust.

"There was a tenseness," Todd told MSNBC's Chris Matthews. "I couldn't see chemistry between John McCain and Sarah Palin. I felt as if we grabbed two people and said 'here, sit next to each other, we are going to conduct an interview.' They are not comfortable with each other yet."

Todd, who was remarking on the interview conducted by NBC's Brian Williams (he was in the room), speculated that the candidates had come to the realization that "they are losing" the campaign, and guessed that McCain may have begun to hold his vice presidential choice responsible for his dwindling White House chances.
