Hillary Clinton and Barack Obama are running even in Pennsylvania in a Zogby poll conducted April 15-16. Clinton leads Obama 45 percent to 44 percent with a 4.1 percent margin of error. Zogby reports a “huge” gender gap with Obama leading Clinton among men voters by 15 points and Clinton having the same margin over Obama among women voters. The poll also says that “Pennsylvanians by a two to one margin are more likely to agree with supporters of Obama that voters in Pennsylvania are bitter about their economic situation than with Clinton and critics of Obama that he is an elitist who does not understand working people.”
