The Massachusetts primary elections are nearly upon us-- they go down on September 9!--which means it's time for The Scrum's first-ever #MaPoli Prediction Challenge.

Your mission is simple: tell us who will win and what percentage of the vote they'll get on Sept. 9 in our favorite statewide races (see below).

After the votes are tallied, we'll figure out which of you came closest to the final results. You'll see how your predictions stack up against other political junkies in the region – as well as The Scrum’s David Bernstein, Peter Kadzis, and Adam Reilly.

This is your chance to claim your rightful mantle as the "Nate Silver of Massachusetts politics." You also might get your hands on a 1st edition one-of-a-kind Scrum T-shirt and a chance to crow about your accomplishments on the first post-primary edition of The Scrum podcast.

So have at it! You have until 11:59PM on 9/8/14 to fill out your predictions in the form below.

The Prediction Challenge has now ended. Thanks for sending in your guesses! We'll have the results tomorrow (9/10/14).
