President Obama and his Republican rival, Mitt Romney, tangled over their varying approaches to foreign policy in dueling “60 Minutes” interviews that aired Sunday, with the president brushing off Romney’s charge that he has been weak on national defense and charging that if Romney “is suggesting that we should start another war — he should say so.”

 Obama’s comments aired after he said last week that, over the course of his presidency, he’s learned “you can’t change Washington from the inside,” but with the help of people across the country. But, he said, “One of the things I’ve realized over the last two years is that that only happens if I’m enlisting the American people much more aggressively than I did the first two years.” 
 
 Still, “change has happened and positive change for the American people,” Obama said, pointing to the passage of his health care law and reforms to the financial services industry. But the Republican candidate again refused to name the specific tax deductions and exemptions he would phase out, insisting that he and his running mate Paul Ryan would work out those details with Congress. Though “the devil’s in the details” on taxes, “the angel is in the policy, which is creating more jobs.”

 Under his plan, all tax rates would be cut by 20 percent, Romney said, but because most exemptions and deductions would be eliminated, most Americans would wind up paying about the same in taxes that they do now.
– President Obama is unleashing the latest attack on Mitt Romney's taxes, following the candidates' dueling appearances on 60 Minutes last night, referencing his 47% comments as well as questions over his own tax rate. "Maybe instead of attacking others on taxes, he should come clean on his," intones the ad, which the AP notes begins airing today in Ohio. Highlights from 60 Minutes: Taxes were in the spotlight during Romney's interview, as he defended his own 14.1% tax rate, Politico reports. It's the "right way to encourage economic growth—to get people to invest, to start businesses, to put people to work," he said. Romney also discussed health care, pointing out that an uninsured heart attack victim isn't left to "sit in their apartment and die." Instead, there's the ER: "We pick them up in an ambulance, and take them to the hospital, and give them care. And different states have different ways of providing for that care." Interesting, notes the Huffington Post, because Romney said the opposite on Morning Joe in 2010: "Look, it doesn't make a lot of sense for us to have millions of people who have no health insurance and yet who can go to the emergency room and get entirely free care for which they have no responsibility." Obama was similarly on the defensive, notes the Los Angeles Times, as he responded to Romney's suggestion he's been weak on defense. If the former governor "is suggesting that we should start another war, he should say so," Obama said. The president acknowledged the frustrations of his job, Politico adds. His "biggest disappointment": not changing "the tone in Washington." "I’m the first one to confess that the spirit that I brought to Washington, where we weren’t constantly in a political slugfest but were focused more on problem-solving ... I haven’t fully accomplished that," he said.
