With exactly four weeks left for ballots to be cast in the 2022 midterm elections, the landscape for control of the Senate is shifting again.

The field has moved slightly back in Republicans’ direction, in part, because of a natural tightening closer to November as the races come into focus for more people, but also because of a deluge of television advertising in key races supporting GOP candidates.

The Senate Leadership Fund, a superPAC aligned with Republican Senate Leader Mitch McConnell, has spent $52 million on TV ads in just the past two weeks, according to the ad-tracking firm AdImpact.
