Gallup is out with new numbers about President Obama's health care bill. According to the poll, 47 percent favor a repeal of the law, should a Republican president get elected and 44 percent oppose it. Not surprisingly, Republicans favor repeal by 87 percent and Democrats oppose it by 77 percent.

More importantly, 72 percent of Americans believe that the law's individual mandate to purchase health insurance is unconstitutional, including 56 percent of Democrats.

As Philip Klein has noted, that makes for some interesting presidential politics this fall.
