CINCINNATI, Ohio Democrats are resuming the controversial practice of meddling in Republican primaries in the hopes of advancing candidates they believe to be weaker opponents in a general election, this time spending to elevate Donald Trump s choice in Ohios U.S. Senate primary next week.

Senate Majority PAC, a group closely aligned with Senate Majority Leader Chuck Schumer, is behind another super PAC, Duty and Country, thats on TV in Ohio with an ad touting Trumps endorsement of car dealer and blockchain entrepreneur Bernie Moreno, Politico first reported . The ad calls Moreno too conservative for Ohio with the aim of boosting him with GOP primary voters just days before voting ends Tuesday.

Senate Majority PAC confirmed its all part of a $2.7 million digital and TV ad buy highlighting Morenos Trump ties.

When Ohio voters head to their polling place they deserve to know the truth about Bernie Moreno and the truth is that Moreno is a MAGA extremist who embraced Donald Trump, just like he embraced his policies to ban abortion nationwide and repeal the ACA, said spokesperson Hannah Menchhoff.

A video of the ad posted on YouTube Wednesday has since been removed .

Ohio is one of the countrys top Senate battlegrounds this year, with Democratic Sen. Sherrod Brown fighting for another term in a state thats trended redder since Brown was first elected in 2006. Besides Montana, Ohio is the best chance Republicans have to retake the Senate.

Senate Majority PAC has meddled in Montanas primary, too, funding a PAC that ran ads against the expected GOP nominee, Tim Sheehy.
