6:09 PM PT: Now we're up to 53-46 with 75% reporting. It's gonna be over soon.
6:16 PM PT: And there we go: The AP has called the race for Ed Markey. Way to go!
7:13 PM PT (Steve Singiser): With over 99 percent reporting, the final margin points to a victory for Democrat Ed Markey of almost precisely ten percentage points. Markey will top out at 55 percent, in all probability, with Gabriel Gomez at 45 percent. This is a slightly wider margin than the Warren-Brown 2012 race. The big story may well be the absolutely anemic turnout. Fun fact: the combined totals of Ed Markey and Gabriel Gomez are less than 100,000 votes higher than Scott Brown's total in the 2010 special election by himself. That said, a win is a win is a win, and in the final analysis, it really wasn't all that close. With only some insignificant stragglers still in the pipeline, we're calling it a night. Thanks for hanging out with us tonight!
