WASHINGTON (AP) — Democrats in and around President Barack Obama's campaign are targeting Republican Mitt Romney by drawing on lessons from the 2004 campaign run by Republicans and President George W. Bush against Sen. John Kerry seven years ago.Kerry and Romney are parallel candidates. Both are wealthy men with Massachusetts roots who have a presidential air but suffer from a stiff bearing.Even before Romney has won a single nominating contest, Obama's camp is singling him out as a fickle politician and is preparing to go straight at Romney's perceived strength — his record as a businessman. It was a strategy Republicans used against Kerry, who had to fend off charges of flip-flopping and whose strength as a decorated Vietnam veteran was undermined by attack ads.
