John McCain has released the first two ads of his 2010 Senate reelection campaign, and he's got some sharp words for President Obama, possibly the sharpest he's offered yet.

"President Obama is leading an extreme, left wing crusade to bankrupt America. I stand in his way every day. If I get a bruise or two knocking some sense into heads in Washington, so be it. I'll keep fighting for jobs and economic growth for Arizona as long as I'm in the Senate," McCain says in one of them.

"My lot in life has been to wage war against wrong, like today's massive spending at the worst possible time," he says in the other. A narrator calls McCain "Arizona's last line of defense" against Obama's agenda and says McCain leads the charge against "ridiculously unaffordable ideas like government-run health care." Conveniently for the McCain campaign, it appears that the only place to listen to the ads, other than Arizona radio stations, is here, on the campaign's contribution-form web page.

McCain has been critical of Obama's agenda, as conservatives Republicans are wont to be. But he hasn't really sought out public forums to level those attacks since Obama entered the White House. Perhaps a tough reelection race changes things: a few liberals have speculated for some time that he could lose in 2010, and a November Rasmussen polls showed him running neck-and-neck with former Rep. J.D. Hayworth.
