Results: AP | CBS | CNN | DMR | Google | NYT | Politico
6:39 PM PT: Of counties reporting results: Santorum leads in 24 of them. Ron Paul has the lead in 15 of them. Mitt Romney in 12 of them. Gingrich? One.
6:44 PM PT: Man, this thing is insanely close. All three top guys are at 23%. Romney has 7,844 votes, Santorum 7,726 and Paul 7,655. 31% reporting.
7:14 PM PT (kos): A huge apology for the tech problems, guys. We've dealt with much larger traffic than tonight, so it's not that. The database is simply freaking out, and the tech team is trying to wrestle it down. We'll make sure to track the source of the problem as soon as we can to make sure it doesn't happen again.
7:15 PM PT (Steve Singiser): Apologies. Looks like we're back and running. With 48% in, Rick Santorum has moved into the narrow lead at 24.4%. Mitt Romney now runs second at 23.8 percent. Ron Paul now has slid back a bit, but is still clearly in third at 21.9 percent.
