"I appreciated his reminder that we can disagree while still being respectful of each other. I've said it before, and I'll say it again - Senator McCain has served this country with honor, and he deserves our thanks for that," Obama told a north Philadelphia crowd, to a mix of heavy boos and cheers.

At an event Friday in Minnesota McCain referred to Obama as a "decent person," and praised him as a "family man" after two voters expressed fear over Obama being elected.
Obama, however, quickly dispensed with polite talk Saturday, and pivoted to his main campaign trail argument: that McCain is out of touch on the economy.
"Senator McCain's campaign manager actually said that Senator McCain wasn't talking about the market because there's just not much a candidate for President can say - and they aren't sure what he'd say each day even if he did talk about it," Obama said.
"But here's the thing Philadelphia. They can run misleading ads, and pursue the politics of anything goes, they can try to change the subject. They can do that what they want to do because the American people understand what's going on - but it's not going to work. Not this time."
