Hillary Clinton's refusal to drop out actually did Obama a huge favor (and I'm not being sarcastic for once)

Today's Electoral-vote.com (one of the best sites covering the election) talks about the major influx of newly registered Democratic voters, showing how in every state except New Mexico the Dems have registered far more new voters than Republicans. Some of this is attributed to the primary dragging on til the very last state:

All those (Obama) Democrats who were moaning that Clinton's refusal to give in was going to hurt the party need to eat a second helping of crow tonight. Her persistence led to huge registration gains which may serve the party well in November.

True enough, I'll eat some crow. For years I wondered why the Democrats didn't focus more of their energy on registering voters in poor, economically struggling areas. Then Howard Dean took over as DNC chair and now they do. Of course, it's possible a lot of new voters registered Democrat just to vote in the primary, when they might actually be Republicans (like Limbaugh's Operation Chaos or whatever it's called) or independents. But still, these figures are yet another lucky alignment of the stars for this November.
