Ten in a row - It's Obama, with a healthy double-digit lead at 5% of the vote counted. Right now it's about 55-43% over Hillary who is now giving a speech in Ohio.
Interesting YouTube moment to come: according to the Fox News reporter for the Clinton campaign, the intro speaker for Hillary's speech was saying some not-nice things about Obama. It sounds like the crowd started to turn against him. Hmm.
Update - Sorry, this makes it nine states in a row, although I'm assuming that Hawaii will back her native son once the votes are counted late tonight.
