Good morning, Washington. It’s Primary Day, and so your Morning Roundup has gone all politics, all the time! (Don’t worry, we’ll get back to the few other non-Primary news stories soon enough.) It wouldn’t be Primary Day without voting issues, would it? The District’s Board of Elections and Ethics reports that a handful of the city’s polling places had issues with opening their new touch-screen voting machines, leading to delays and a reliance on paper ballots. The issues are apparently due to “training issues.” Twitter user antheawatson told us that at Dunbar High School, poll workers “had the manual out” and that it didn’t “seem like the poll workers are adequately trained on the electronic poll books.” At this editor’s precinct (Ward 1, Precinct 22), the new machines worked, but the polling place was short-staffed, and waiting on backups, leading to long lines — paper balloting was being pushed hard, too.

Of course, the biggest story of the day today will be turnout. Will the absolutely gorgeous weather today push turnout higher? Not if early returns have anything to say about it — several tipsters reported very short or no waits at precincts where the equipment was working properly. Here’s an interesting note — with many people expected to register today, there will be a lot of provisional ballots out there. If the race is really close, they might play a large role — and BOEE will not officially count the ballots until September 25. Could we possibly not know the results of the mayoral election for another 11 days? The Examiner’s Freeman Klopott sure thinks so; Klopott notes that, based on the last few primaries, absentee and provisional ballots could make up almost 10 percent of the total count.

As far as the candidates go, Mayor Adrian Fenty kicked things off this morning with a bleary-eyed pep rally (who has pep at 5:30 a.m.?), followed up by an appearance on MSNBC’s Morning Joe — Fenty seemed confident, stating “Well, we’re going to win,” while refusing to answer a question about a potential party switch if he loses. Vince Gray voted this morning at the Washington Senior Wellness Center in Ward 7, hugging Kwame Brown in the process. (If they both win today, let’s see if they’re so willing to embrace one another come budget crunch time.) Both candidates went with the paper ballot.

Be sure to send us your Primary Day experiences — pictures, stories, long lines, issues with the equipment, whatever — to tips@dcist.com. Or, you can tweet at us on Twitter @DCist_updates. (Don’t forget to use the #VoteDC hashtag!) Our Martin Austermuhle is setting up shop at BOEE headquarters, and we’ll have updates from him and our readers throughout the day as they come in.

Your Final Primary Notes: TBD’s blogger straw poll (we didn’t participate) goes for Fenty, Kwame Brown…WaPo’s Petula Dvorak on the spectacle of the election…Fenty and Gray’s last substantive debate was about parking…Something we’re keeping an eye on: City Paper’s Lydia DePillis is shadowing Phil Mendelson, while TBD’s Sommer Mathis is (trying to) shadow Michael D. Brown…The encyclopedia of cronyism.
