"The McCain campaign's lies make it clear that John McCain would rather lose his integrity than lose this election. The fact is, John McCain has voted for millions in earmarks and his running mate has requested more pork per person than any governor in America -- including $2 million to study the mating patterns of crabs. Barack Obama has stood up to the lobbyists and corruption in Washington, and will bring real change that puts middle-class families first," said Obama campaign spokesman Tommy Vietor.
I don't think the Obama camp should go in this direction. Fact is, Obama has also voted for (and requested) millions in earmarks. $740 million to be exact.
