Democrats have criticized Collins, who is running for reelection in Maine, for her earlier procedural vote on a motion to advance the OBBBA to the Senate floor for consideration. But the ad ignores the fact that she ultimately voted against the bill instead of supporting it.
The nearly 30-second ad is sponsored by a group called Affordable Maine, which, as of Aug. 12, had spent more than $473,000 to air the TV and digital ad, according to AdImpact.
Collins is facing Democrat Troy Jackson, a former state Senate president, in the toss-up race.
