It probably won't be known until November whether this prolonged Democratic primary process is hurting the party. But with political participation at record highs around the country, it can't be all bad.

Indiana Democratic Party Chairman Dan Parker believes the long primary season has been beneficial, according to the Indianapolis Star's Matthew Tully.

"From a party building standpoint, this has just been fantastic," Parker said.

Parker pointed to a dramatic increase in voter registrations, the heavy turnout expected today and the "record amount of money" state Democrats were able to raise at their Jefferson-Jackson Day dinner Sunday. (Sens. Clinton and Obama both spoke at that event.) He also talked about the valuable experience Indiana Democrats gained by working side-by-side with the presidential campaigns.

Of course, the primary has also divided many Democrats. And the presidential contest has overshadowed the party's gubernatorial primary between Jim Schellinger and Jill Long Thompson.
