The Republican primary may be a circus, but it’s not making lots of swing-state voters feel better about President Obama. According to a new CBS/Gallup poll, the two leading GOP candidates, Newt Gingrich and Mitt Romney, would beat Obama in every swing state, including Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia, and Wisconsin. Romney leads by 5 percent, and Gingrich by 2 percent. But do polls matter this far out? An NBC/Marist poll shows Obama with a comfortable lead over both GOP candidates in Florida and South Carolina.
