Team Romney projects only a 6-8 point victory tonight, but, with a slew of new polls, including yesterday’s Suffolk University poll showing Mitt Romney up 47 percent to 27 percent over Newt Gingrich, a double-digit win seems more likely. More important than the final raw number though, is how Romney does with differing demographics across the Republican base. Only one poll, the NBC News/Marist poll, has released tables showing how the candidates are fairing with different population segments, and the results look good for Romney.

Like his win in New Hampshire, the Marist poll shows Romney winning households making $75,000 or more (49-27) and those making less than $75,000 (37-28). He is winning both the college graduate vote (44-25) and the non-college graduate vote (40-29). He is winning among Evangelicals (34-28), in the Panhandle (37-25), in central Florida (44-30), and in south Florida (49-31). Romney even wins among conservatives (47-28) and moderate Tea Party supporters (39-32). The only groups Romney loses are “strong Tea Party supporters” (27-40) and “very conservative” Republicans (24-36).
