Yeah it's the super PAC's direct fault here:

The Defending Main Street super PAC spent thousands of dollars on an attack ad to audiences thousands of miles away from the Maine Senate race it was targeting.

The ad hit Maine Democratic Senate candidate Troy Jackson on the issue of taxes and cost of living in the state.

“Maine can’t afford Troy Jackson and all his taxes,” the ad said.

“It’s clear these people don’t know anything about Maine.”

The group, which describes itself as the “most effective independent expenditure organization supporting the governing wing of the Republican Party,” paid for the ad to attack Jackson, who’s mounting a challenge to incumbent GOP Sen. Susan Collins. Both candidates have made cost of living a central plank of their campaigns in the run-up to the midterm election on November 3.
