The top five for the CD1 race:

Almost everyone guessed within two or three points of the actual result. There wasn't anything surprising in this race since the primaries, when Pingree locked things up.

Frary seems to have outperformed some very low expectations in the CD2 race. Some even predicted the professor garnering less than 20% of the vote.

Duke predicted Frary winning this one 50-49 (maybe he worked for the campaign) and Jacob R. predicted a 71-29 landslide victory for the Republican (I'm hoping it was a typo), ending his chances of winning the pool.
