President Obama isn't just attacking Mitt Romney's policy proposals -- he's attacking his opponent's campaign as well.

"Every few days he keeps on saying he's going to 'reboot' this campaign and they're going to start explaining very specifically how this plan is going to work, and then they don't," Obama said yesterday in Virginia Beach, referring to Romney's tax cut plan.

On Wednesday in Ohio, Obama said of Romney: "No matter how many times they try to 'reboot' their campaign, no matter how many times they try to tell you they're going to start talking specifics really soon, they don't do it."

The president and aides are picking up on reports of Romney campaigning in-fighting, in light of polls giving Obama a lead in the presidential race.

Romney and aides say tax cuts will help spur an economy that is stagnating on Obama's watch.

Aides also say the Romney campaign is doing just fine, and zeroed in on Obama's failures of economic leadership.

"President Obama's policies have devastated the middle class," said Romney spokesperson Amanda Henneberg. "Unemployment remains chronically high, poverty has increased, and incomes have fallen. It's no surprise that the president would try to cover up his record of failure with more false, negative attacks."
