There will also be a special election in Virginia's SD-38 that will either cement the Republican majority or hand the chamber back to the Democrats. Our guide to both races can be found here. Poll close in Virginia at 7:00 PM ET and in Alaska at 12 AM ET and we'll be bringing you tonight's results as they come in. You can keep track of the winners just below.
Tue Aug 19, 2014 at 11:06 PM PT: There are two Dan Sullivan's on the statewide ballot tonight. One is the Senate candidate and former State Natural Resources Commissioner. The other is the Anchorage Mayor, who is easily winning the Republican primary for lieutenant governor. In Alaska governor and lieutenant governor candidates are nominated separately but shackled together in the general on one ticket.
Tue Aug 19, 2014 at 11:06 PM PT: 32 percent in and things are a little closer again for U.S. Senate. Sullivan leads Miller 39-33, with Treadwell at 25.
Tue Aug 19, 2014 at 11:13 PM PT: A good chunk of that vote was from Miller's base outside Anchorage, with some of the city itself thrown in. Some rural areas like Kodiak also came in.
The needle didn't change too much on Measure 1: It now leads by 478 votes.
Tue Aug 19, 2014 at 11:27 PM PT: It looks like quite a bit of Mat-Su's in. Miller doesn't seem to be where he needs to be right now.
Tue Aug 19, 2014 at 11:32 PM PT: Now at 38 percent in and Sullivan remains ahead 39-33. Measure 1 is down now, losing by 1,069 votes. This is the largest gap of the night.
Tue Aug 19, 2014 at 11:36 PM PT: That last batch had more Mat-Su, with Anchorage and Kenai mixed in. Miller's just not doing what he needs to do.
12:03 AM PT: 56 percent reporting and Sullivan's lead is back to 40-33. This one is over. Sullivan will face Democratic Sen. Mark Begich is one of the most hotly contested races in the country. Referendum 1 remains tight, with No up 2,066.
With that, we're calling it a night here. Thanks for reading and see you next week for Arizona, Florida, and the OK-05 GOP runoff.
