Vice President Joe Biden campaigns Tuesday in the battleground state of New Hampshire and on Mitt Romney's home turf in Massachusetts. The topic: the economy? The question: Will Biden ratchet up the Bain attack?

Romney, meanwhile, has fundraisers in New York and Connecticut. N.J. Gov. Chris Christie will join him at the New York event. It will be interesting to see if there is a response to the Bain attacks — from Romney, Christie or both.

There are Republican presidential primaries Tuesday in Arkansas and Kentucky that will add to Romney's delegate tally.

Rep. Paul Ryan, R-Wis., speaks at the Reagan Library in Simi Valley, Calif. The title of his speech is "A Rendezvous with Reagan's Legacy: Lessons for 2012." Ryan has been mentioned as a possible vice presidential candidate.

And then there is this: The John Edwards jury is in its third day of deliberations. Is Tuesday the day for a verdict?

President Barack Obama on Monday acknowledged "risks" in his decision to withdraw U.S. combat forces from Afghanistan by the end of 2014 but said war-weary Americans can't wait for that strife-torn country to be "perfect."

"I don't think that there is ever going to be an optimal point where we say, this is all done, this is perfect, this is just the way we wanted it and now we can wrap up all our equipment and go home," Obama said at a press conference at the end of a two-day NATO summit in his hometown of Chicago.

Obama also said the Pentagon isn't giving him an unrealistically rosy picture of Afghanistan. "I can't afford a white-wash. I can't afford not getting the very best information in order to make good decisions."

"I should add, by the way, that the danger a lot of times is not that anybody is purposely trying to downplay challenges in Afghanistan. A lot of times it's just the military culture is 'we can get it done.'  And so, their thinking is, 'how are we going to solve this problem?' not boy, 'why is this such a disaster?'"

The alliance, which had already embraced the 2014 withdrawal date, voted to hand Afghan forces the lead in combat operations starting in mid-2013. Building up the country's military and police — and its economy — are vital to the NATO-led International Security Assistance Force's planned draw-down.

"We leave Chicago with a clear roadmap," the president said. "Our coalition is committed to this plan to bring our war in Afghanistan to a responsible end."

"This is a process and it's sometimes a messy process, just as it was in Iraq. But think about it. We've been there now 10 years," Obama said. "And the Afghan Security Forces themselves will not ever be prepared if they don't start taking that responsibility."

In the spotlight of the world stage, President Barack Obama on Monday unapologetically defended his campaign's attacks on Mitt Romney's record at the private equity firm Bain Capital and vowed to keep up the onslaught all the way to November.

"This issue is not a distraction," Obama defiantly declared at a press conference wrapping up a NATO summit in his hometown of Chicago. "This is what this campaign is going to be about."

"If your main argument for how to grow the economy is 'I knew how to make a lot of money for investors,' then you're missing what this job is about," the president said, evidently relishing the opportunity to knock Romney.

"It doesn't mean you weren't good at private equity, but that's not what my job is as president. My job is to take into account everybody, not just some. My job is to make sure that the country is growing not just now, but ten years from now and 20 years from now," he said.

Obama's campaign has drawn fire, including from Democrats, for ads focused on the fate of GST, a Kansas City steel mill Bain bought in 1993 and put into bankruptcy in 2001. Romney left Bain in 1999, but maintained an interest in the firm.

In January, the Reuters news agency published a long analysis of Romney and Bain's record with GST, along with his record in private equity overall. (Of note: The plant's owners approached Bain Capital "because it had earned a sterling reputation for turning companies around.")

The Romney campaign has hit back by portraying Obama's criticisms of Bain as an attack on capitalism, and wasted no time in turning Democratic Newark Mayor Corey Booker's description of the attacks as "nauseating" into an ad.

"President Obama confirmed today that he will continue his attacks on the free enterprise system," Romney said in a statement after the embattled incumbent's remarks.
