The Democratic race....

things are surely getting interesting in Pennsulvania these days. There are now more than 4 million registered Democrats in the state, a huge surge in the final days for folks to register and qualify for this month's Democratic primary showdown with Barack Obama and Hillary Clinton.

And momentum seems to be on Obama's side. According to a newly released Quinnipiac poll, Clinton's lead has been cut to 6 points (50 to 44 percent), down from a 9 percenta point lead last week.

There's been a lot of talk about having the superdelegates bring this to a quick end before the duel causes serious damage to the party's chances in November. But...that might not be necessary if Obama can pull off the upset in Pensylivania. There's no way Clinton could continue if that happened.

Pennsylvania voters hold the power to either continue this contest or bring it to an end.
