Results: Colorado | New York | Oklahoma | South Carolina | Utah
7:16 PM PT: Polls are now closed in Utah, by the way, though I don't think it will be a very interesting night there. 2% is reporting in UT-Sen (R), and Sen. Orrin Hatch is crushing Dan Liljenquist 70-30.
7:22 PM PT: Just something slightly noteworth: Dem Rep. Greg Meeks in NY-05 is only at 60% with 7% reporting. He won't lose—the field against him is split three ways—but this could be a sign of weakness portending a future serious challenge.
7:23 PM PT: A good lesson in why you shouldn't get too invested in the early numbers: Charlie Rangel just swept out to a big 56-29 lead over Adriano Espaillat in NY-13 (D), after trailing all night. Still, only 16% is reporting, so that may yet change again.
7:24 PM PT: Grace Meng looks like she's really romping in NY-06 (D). 23% counted and she's at 61%. Rory Lancman is at just 19%.
7:25 PM PT: Rep. Nydia Velazquez continues to cruise in NY-07 (D). She's at 65-25 over Erik Dilan with 27% reporting.
7:26 PM PT: No surprise: NY-09 (D) called for Rep. Yvette Clarke, who has 87% of the vote right now.
7:27 PM PT: NY-18 (D) has gotten a bit tighter, but Sean Maloney still has a sizable lead over Rich Becker, 46-31 with 41% reporting.
7:28 PM PT: Nate Shinagawa continues to do well in NY-23 (D). He's up 58-36 over Leslie Danks Burke with 55% reporting.
7:29 PM PT: NY-Sen (R) has been called for Wendy Long.
7:31 PM PT: In NY-04 (R), Fran Becker has won his primary, earning the right to a rematch with Dem Rep. Carolyn McCarthy. Becker came a little too close for comfort in 2010, losing by about 7 points.
7:33 PM PT: It really seems like Republican Rep. John Sullivan is going to lose in OK-01. After a new vote dump, we're up to 39% reporting, and Jim Bridenstine's 6-point lead is unchanged. Amazing.
7:34 PM PT: Looks like it's over in NY-06 (D):
We have our first winner of the night: Grace Meng is now declaring victory in #NY06.

7:38 PM PT: I think the most interesting races left in New York are probably NY-13 (D) and maybe NY-18 (D). Everything else seems to be on a pretty clear trajectory.
7:39 PM PT: Sweet relief: The AP calls NY-08 (D) for Hakeem Jeffries, who beats Charles Barron handily. In this super-blue district, Jeffries is the guaranteed victory in November.
7:41 PM PT: Charlie Rangel's at 55-29 over Adriano Espaillat with 33% now reporting. It's not impossible, but it's going to be hard for Espaillat to make that back up.
7:42 PM PT: The AP has finally called OK-02 (R): It will be a runoff between Markwayne Mullin (43%) and George Faught (23%).
7:44 PM PT: The AP calls NY-07 (D) for Rep. Nyedia Velazquez, who handily turns back a challenge by NYC councilman Erik Dilan.
7:45 PM PT: And NY-17 (R) is called for Joe Carvin. Dems won't get the chance to face white supremacist Jim Russell a second time. Too bad.
7:50 PM PT: Still stuck at 3% of the vote counted in Utah. I guess you'd have to call it a root beer break....
7:55 PM PT: The AP calls NY-06 (D) for Grace Meng, who declared victory a little while ago. Looks like Rory Lancman will finish in 2nd.
7:55 PM PT: NY-23 (D) is called for Nate "The Great" Shinagawa. He earns the right to take on GOP freshman Tom Reed in November.
7:57 PM PT: A runoff has finally been called in OK-02 (D), between Rob Wallace (46%) and Wayne Herriman (42%).
7:58 PM PT: The liveblog continues here.
