ABC News' Bret Hovell Reports: Sen. John McCain said Wednesday that if elected president, he would clean up the nation's political discourse, and called for an end to negative campaign ads.
"I'm going to raise the level of political dialog in America," McCain, R-Ariz., said at a campaign rally in central Michigan, "and I'm going to treat my opponents with respect and demand that they treat me with respect."
As president, McCain said, he'd be able to work well with members of Congress on the Democratic side of the aisle.
"We're going to get a dispute and a debate done, but in a respectful fashion," McCain said. "And I know how to reach across the aisle to [the Democrats], and I'll ask you to tell them to reach across the aisle to me."
Fresh from his New Hampshire primary victory, McCain said he hopes for an end to negative advertising in political campaigns.
"It's time we did away with a lot of this political rhetoric at the level we're at, including these negative ads. Nobody likes these negative ads. You want to know what we're for, not who we're against."
McCain faced several negative advertisements leveled against him by rival Mitt Romney, the former Massachusetts governor, leading up to the Granite State's first-in-the-nation primary.
The McCain campaign bought television time for one negative ad of his own in New Hampshire, which the campaign contends was necessary to respond to a Romney ad that was misleading about McCain's immigration policy, suggesting McCain supported "amnesty" for illegal immigrants.
That ad quoted the Concord Monitor, calling Romney a "phony."
"You want to know what we're for," McCain said, condemning negative ads, "not who we're against."
