HEMPSTEAD, N.Y.--Sen. John Kerry (D-Mass.)--who played Mitt Romney for President Barack Obama's debate prep-- scorched Romney as fake when it comes to bi-partisanship while talking to reporters before the second presidential race on Tuesday.

"Country be warned," Kerry said at the media file center and spin room at Hofstra University in this Long Island suburb.

Kerry said he anticipated that Romney may bring up his work with Massachusetts state lawmakers while he was governor--especially on his signature health care bill as bi-partisan credentials.

"Now he's running away from it nationally and says he's going to repeal it, his own plan!" Kerry said. "This is artistry. This is the most flim-flam-est political artistry I've ever seen."
