Via The Corner, pardon my skepticism over this:

CONCORD, N.H. (AP) – A prominent New Hampshire Republican who was a delegate to the party’s nominating convention is quitting John McCain’s campaign and endorsing Barack Obama.

Fred Bramante says he is resigning as a member of McCain’s New Hampshire Leadership Committee. He had been a co-chairman of Mike Huckabee’s New Hampshire presidential campaign and joined McCain after the former Arkansas governor dropped out of the race.

Bramante, a member of the state Board of Education, said he opposes McCain’s support of school vouchers, which he said politicians must abandon if they want to improve education.

Bramante said he’s concluded that McCain would do little to improve education, while Obama supports new and innovative ideas.

Hold on. I can understand an opposition to school vouchers (though don’t agree with it). But the guy only switches over to Obama with less than a week before the election and over the voucher disagreement? McCain has supported school vouchers consistently over the years. If that issue is so important to Bramante that it decides who he votes for, why didn’t he check where McCain stands on it before joining a leadership committee for the campaign?

I’m not buying the excuse.
