Why the winds are shifting toward Obama - CNN.com
In a mid-November survey, when asked which candidate they were more likely to support, registered voters gave Mitt Romney a lead of 4 percentage points over Obama, 51% to 47%. The mid-December survey found an 11-point switch; Obama now has a 52%-45% edge over Romney. Against Newt Gingrich, Obama has a 16-point lead, 56%-40%. (Ironically, the one Republican candidate who does as well against Obama as Romney is Rep Ron Paul, trailing by the same 52%-45% margin.)
