The polls have closed on this, the April 3 D.C. primary. Follow here for the results as they roll in.

11:30 p.m.: Wow. With all precincts in, Orange takes a lead of just over 1% over Biddle. But that doesn’t mean victory—absentee, provisional and curbside votes have yet to be counted, and if those bring the margin within 1%, a recount takes place. The At-Large race will remain unsettled for at least 10 days.

11:05 p.m.: NBC4 is calling the Ward 4 race for Muriel Bowser. That’s three-for-three on incumbents keeping their seats (also Evans), and Alexander and Michael D. Brown likely to win another term.

10:50 p.m.: With 78% of precincts reporting, Biddle has climbed to 40%, Orange is at 37.82%. Still, it’s too close to call—and might be for a while. There are close to 4,000 absentee ballots that were sent out and will be counted within 10 days.

10:30 p.m.: With 84 precincts in (58%), Biddle is still keeping a narrow lead over Orange, 39.48% to 38.34%. Muriel Bowser and Yvette Alexander looking like re-elects.

10:20 p.m.: It’s looking more and more likely that Marion Barry will be re-elected to a third term on the D.C. Council. With 41% of Ward 8 precincts reporting, he’s at 75%. Patterson’s campaign manager just told me that Patterson well be conceding to Barry.

10:05 p.m.: With 62 precincts reporting (43% of total), Biddle has taken a 1.5% lead over Orange. Alexander has 42%, and her top two opponents each have around 20%.

10 p.m.: It looks like Marion Barry is already claiming victory. In the At-Large race, someone asked what would trigger an automatic recount: anything less than 1% between candidates would.

9:51 p.m.: With 20 more precincts reported (40 total so far), Orange and Biddle are close again, 39-38. Just over 100 votes separating the two. Shapiro at 11, Holness at 7. Yvette Alexander looks to be maintaining, as does Muriel Bowser and Marion Barry.

9:30 p.m.: The first 20 precincts have reported, and Orange has taken a 42-35 lead over Biddle. Shapiro has 10%. Alexander has widened her lead slightly in Ward 7. In both the At-Large and Ward 7 races, it’s looking like the much-feared dividing of opposition votes is happening. Many more precincts left to report, though.

9:10 p.m.: Early vote results are up. Of the 6,000 people that voted early, 2,217 went for Sekou Biddle (40.62%), 2,068 for Vincent Orange (37.89%) and 701 for Peter Shapiro (12.84%) in the hotly contested At-Large race. In Ward 4, Muriel Bowser crushed with 986 (70.48%), while in Ward 7 Yvette Alexander only got 242 (39.16%) votes to Tom Brown’s 135 (21.84%). Marion Barry is also leading (59.77%), as is Michael D. Brown in the Shadow Senator race (62.51%). Everything is here.

9:00 p.m.: So, how do we know that the folks at the D.C. Board of Elections aren’t sitting in some back room engaging in massive voter fraud? We’ve got a live webcam view of the tallying room from our perch in a conference room nearby.

8:45 p.m.: We can probably jump ahead and say that Mitt Romney is going to clinch the Republican presidential nomination in D.C. (That’s 19 delegates, all told.) As for the unopposed races, it’s probably fair to assume that Councilmember Jack Evans (D-Ward 2) will be winning his race, and Nate Bennett-Fleming will be the city’s next Shadow Representative. (Want to know more about him? Read this.)

8:30 p.m.: So what actually happens now? The polls close, and poll workers go about shutting down voting machines and tallying results. Once that’s done, they hand the voting machine cartridges (basically the media on which all the votes are held) and send them along to the D.C. Board of Elections and Ethics in Judiciary Square. By truck. And yes, if there’s a lot of traffic, the results can be delayed. Once they get to the board’s offices, they’re fed into machines that upload the results here. If all goes well—it did for last year’s special election—everything should be uploaded smoothly and relatively quickly. If not—like the 2010 mayoral primary—we could be here until late.
