Presidential candidates enter full campaign mode.

Barack Obama - Officially, the president’s scheduled trips to Virginia, Ohio, North Carolina and other key states are to sell his American Jobs Act to the American public.

Rep. Michele Bachmann - In an effort to regain some of the steam that Texas Gov. Rick Perry has siphoned away from Rep. Michele Bachman’s campaign, Keep Conservatives United, a super PAC supporting the Minnesota lawmaker, has launched a radio ad campaign attacking Perry on his immigration policies. “Michele Bachmann believes employers should be required to check the legal status of people they hire with E-Verify,” the ad says. “Perry doesn’t, so illegals take jobs.”(Photo: AP Photo/Cliff Owen)

Herman Cain - Herman Cain has been touting his 9-9-9 economic plan, which would replace the federal tax with a 9 percent sales tax, 9 percent income tax and a 9 percent corporate tax, and slamming President Obama’s new jobs plan.

Newt Gingrich - Newt Gingrich, like the rest of his presidential rivals, harshly criticized President Obama’s jobs plan the day after he unveiled its details. “Last night proved he has learned nothing, he has no plans, he just has speeches. He said, ‘I’m not engaged in class warfare, but let me bash rich people a bit,’” Gingrich said at a New Hampshire campaign event. “What does he think class warfare is?”(Photo: AP Photo/Cheryl Senter)

Jon Huntsman - Jon Huntsman’s campaign is in desperate need of a spell checker. This week it announced the “endorsment” of three New Hampshire “represenatives,” Politico reports.

But perhaps that’s the least of his problems as he struggles to keep his campaign alive.(Photo: AP Photo/Jae C. Hong)
