A Republican-aligned super PAC is taking aim at Montana Gov. Steve Bullock — not because of the Democrat’s presidential bid, but because of a prospective Senate bid.
The Senate Leadership Fund, an ally of Senate Majority Leader Mitch McConnell, bought a five-figure digital ad campaign attacking Mr. Bullock for spending time outside the state on the presidential campaign trail.
The ad makes no mention of his potential challenge to incumbent Republican Sen. Steve Daines, but GOP sources say that is why the Senate Leadership Fund took the unusual step of hitting a candidate not openly campaigning for the Senate.
