The latest Rasmussen poll of likely voters shows President Obama leading Rick Santorum by 3 percentage points and leading Mitt Romney by 6 percentage points. Obama leads Santorum by the tally of 46 to 43 percent, while he leads Romney by the tally of 47 to 41 percent.

Meanwhile, Quinnipiac’s polling shows Obama leading Romney by 2 points (46 to 44 percent) and leading Santorum by 3 points (47 to 44 percent).  But Quinnipiac also shows Santorum with a higher net favorability rating both overall (+3) and among independents (+3) than Romney has.  Romney’s net favorability is minus-8 overall as well as minus-8 among independents.  The former Massachusetts governor’s net favorability rating has dropped 13 points in Quinnipiac (from +5 to minus-8) since Thanksgiving week.
