Statistical tie. And Frank Newport adds, "There have been minor changes in the shape of the national registered voter preferences for the fall, with John McCain now leading Obama by a slim two percentage point margin, while Clinton has a slight 2-point margin over McCain." The question is, why has Hillary closed the gap? I suspect it's the PA bounce, but the Rev. Wright stuff can't be helping. The Indiana primary should shed some light. The demographics there may be even more favorable to Clinton than Pennsylvania. If she isn't able to recreate her PA victory in Indiana, then there's something wrong with her campaign. If she builds on her victory, then there's something wrong with Obama.
