Interesting material as the McCain campaign gears up for a good fight… From the Politico:

Charlie Black, a McCain senior adviser who is among the best-known figures in Republican politics, said he expects Obama will “probably get a record bounce” now that he has clinched his party’s nomination.

“His nomination is historic, and he’s going to get incredibly favorable press for a week or maybe two,” Black said. “As long as we’re out there and we are getting covered and we’re drawing differences on issues, which is a big part of our campaign, we can bring the bounce back into reach late in the summer.”

The poll warnings are in part of matter of setting expectations, preparing supporters and avoiding the demoralization that could come from the big jump.
