Obama said that in this election there "will be as sharp a contrast between the two parties as we've seen in a generation."
"You have a Republican Party, and a presumptive Republican nominee, that believes in drastically rolling back environmental regulations, that believes in drastically rolling back collective-bargaining rights, that believes in an approach to deficit reduction in which taxes are cut further for the wealthiest Americans, and spending cuts are entirely borne by things like education or basic research or care for the vulnerable," Obama continued.
Obama rejected the idea that Romney would be able to disavow positions he's taken in the primary. "I don't think that their nominee is going to be able to suddenly say, 'Everything I've said for the last six months, I didn't mean.' I'm assuming that he meant it," he said. "When you're running for president, people are paying attention to what you're saying."
