Barack Obama is in front of Hillary Clinton, 56 to 39, in a USA Today national poll. And is beating her 54 to 38 in a N.Y. Times/CBS poll. And edging her 50 to 46 in Texas, according to a CNN poll. (Change from 2.18 poll — Obama up two points, Clinton down four.) And columnist Robert Novak is asking today “who will tell her that it’s over, that she cannot win the presidential nomination and that the sooner she leaves the race, the more it will improve the party’s chances of defeating John McCain in November?”
