Marc Ambinder looks at the exit polls from Indiana and North Carolina and sees some not-so-good news for the Democratic Party:
Forget the horse race numbers for a moment: if the surveys are accurate, the polarization within the Democratic Party has reached critical levels. Nearly six in ten Obama supporters in Indiana say they would be dissatisfied if Clinton were the nominee — that’s (I believe) the high percentage of Obama supporters who have ever said that.
In both IN and NC, two thirds of Clinton supporters say they’d be dissatisfied if Obama were the nominee — I believe that’s the highest number recorded for that question, too.
The percentage of Clinton voters who say they’d choose McCain over Obama in a general election is approaching 40% in Indiana. Put it another way: in North Carolina, less than HALF of folks who voted today for Hillary Clinton are ready to say today that they’d definitely vote for Obama in a general election.
And, as the Washington Post notes, the numbers in Indiana seem to be similar:
Fewer than half of Clinton voters in both states said they would support Obama over McCain in the general election should that be the matchup. More than half of those backing Obama said they would be unhappy with Clinton as the party’s standard-bearer.
If Clinton does decide to stay in the race, this polarization is only likely to get worse.
