AP on the continuing push-poll investigation in NH Dave and Jim over in the Campaign Spot mentioned:

McCain’s campaign immediately called on the attorney general to investigate and decried the effort to besmirch him. Aides suggested the calls were designed by fellow Republicans to embarrass the Arizona senator. “If you look at their list of clients, they’re all Republicans. … They’re a Republican operation, they weren’t hired by Hillary Clinton,” said Chuck Douglas, a former congressman who is a top McCain adviser in New Hampshire.
“It’s obvious it’s one of the presidential campaigns. We’ve long suspected – and still suspect – it’s Gov. Romney who wanted to test the Mormon issue and McCain’s record and see what messages would work. It’s up to that campaign and all the others to just say a very simple statement. It has to come from the top of their campaigns: ‘We had nothing directly or indirectly to do with this 260-page report or the 400 questionnaires that were filled out.’”
Romney’s campaign vigorously denied it was involved, saying the calls were reprehensible.

From Team Romney:

“The Romney campaign had nothing to do with these alleged push polling calls. It is reckless, irresponsible and egregious for the McCain campaign to even mention the Romney campaign in relation to these calls. If they have any proof, let’s see it. If not, Senator McCain should immediately apologize for the actions of his own campaign.”
