As President Obama began to hunker down at a plush resort here for three full days of debate prep, his campaign team signaled the incumbent may steal a page from Vice President Joe Biden and show a more aggressive tone in Tuesday’s second face-to-face showdown with Republican Mitt Romney.

“Gov. Romney has been making pitches all of his life and he knows how to say what people want to hear whether that was during his time at Bain or during the dozens of town halls he did during the primary,” said Obama campaign spokeswoman Jen Psaki said Saturday. “His running mate also left him vulnerable on a number of issues — admitting there was a $5 trillion tax cut, after he denied it, but again failing to explain how they would pay for it, leaving women worried about their ability to make choices about their own health care and failing to articulate their plan for winding down our presence in Afghanistan.”
