8:06pm: Now that polls have closed in Pennsylvania, let's move this block party to a new thread.
8:03pm: 1449 precincts now in, and Conway leads by 49-39. We still have 91 precincts outstanding in Fayette and 96 in Jeffco. After that, we're looking at a lot of itty bitty counties.
7:59pm: In KY-06, Andy Barr has won the GOP nod to face off against Dem Rep. Ben Chandler.
7:58pm: The AP has called KY-03 for Todd Lally, in a major voter backlash against Pizza Hut.
7:55pm: 1341 precincts are in, and Conway's lead has expanded to 50-38. Only 96 precincts in Jeffco remain.
7:52pm: Aaron hears that the Mongiardo camp is worried about low turnout in rural counties.
7:50pm: Ladies and gentleman... the Associated Press has now called your 2010 Kentucky Republican Senatorial nominee... Rand Paul!
7:48pm: 1160 precincts are in, and Conway is up by 49-39. 93 precincts in Fayette remain, and Jeffco remains untouched.
7:41pm: 1004 precincts are in, and Conway leads by 49-38. There are still 127 precincts outstanding in Fayette and 186 in Jeffco. Will that be enough to help Conway hold on? Our crude back of the envelope says maybe not, but I'm also hearing signs of optimism from a source close to the Conway campaign. We'll see!
7:36pm: 838 precincts are in statewide (out of 3575), and Conway leads 51-37. Keep in mind, though, that Jeffco is now well over half in (Conway is crushing by 60-27 there).
7:34pm: And over in KY-03, Air Force vet Todd Lally is beating the somewhat better-funded Pizza Hut franchise baron Jeff Reetz by 53-16. Someone I haven't heard of before today, Larry Hausman, is sitting in second with 25%. Go figure!
7:30pm: Fayette is now half in (giving Conway 52-38 there so far), keeping the score at 47-40 statewide with 572 precincts reporting.
7:23pm: Mongiardo has narrowed the gap in liberal Fayette County -- he's now only down by 51-38 there. Overall, with 509 precincts reporting statewide, it's still 47-40 Conway.
7:21pm: 465 precincts are now in, including an additional 142 from Jeffco, pushing Conway to a 47-40 lead.
7:14pm: 255 precincts in, and Mongiardo leads Grayson by 46-42. Still only 12 of 524 precincts in from Jeffco, though.
7:13pm: Ouch -- so far, Trey Grayson is losing his home county of Boone by 30 points to Rand Paul.
7:08pm: 192 precincts now in statewide (including a handful from Jefferson County, where Louisville is located), and Mongiardo has regained a 45-43 lead.
7:06pm: In KY-06, attorney Andy Barr is leading a very divided GOP field with 69% of the vote. Just under 10% of precincts are reporting there.
7:02pm: With 141 precincts in, Conway has now pulled ahead by 44-43. Note that no precincts in Conway's home base of Louisville have reported yet. Paul's leading Grayson by 55-39.
6:53pm: We're up to 44 of 3575 (still only around 1%). Mongiardo leads Conway 48-39 overall (with a surprising 7% for Deb Darlene Price); Conway is up 52-35 in Fayette County, where he'll need to do well if he's going to have a chance (it's the location of the college town of Lexington and the state's 2nd most populous county). Over in KY-06, Andy Barr seems to have the edge in the GOP primary, at 66% with 3% reporting. (C)
6:37pm: Alright, time seems to be progressing in the normal manner again. With 10 precincts apparently reporting, Mongiardo leads Conway 51-37. Paul leads Grayson 50-43.
6:31pm: I believe we can call this the Curious Election of Benjamin Button.
6:24pm: It looks like the AP (and, subsequently, the Politico) are having some early jitters -- for some reason, the number of precincts reported keeps going down on their pages, but the total number of votes is increasing. Whatever the case, Mongiardo now leads Conway 50-38, and Paul leads Grayson by 48-45. Keep in mind that these early counties are generally expected to be more favorable territory for Mongiardo.
6:16pm: With just over 1% of precincts reporting, Mongiardo leads Conway by 56-34. Paul leads Grayson by 49-43.
Polls will close in the Eastern time zone portions of Kentucky at 6pm, and in the CT areas an hour after that. We'll be using this thread to follow the returns in the KY-Sen, KY-03, and KY-06 primaries. We'll check in with Pennsylvania (8pm ET), Arkansas (8:30pm ET), and Oregon (10pm 11pm ET) later in the evening.
