Santiago—Getty ImagesThe fierce and bipartisan backlash to gubernatorial candidate Vivek Ramaswamy's decision to feature his opponent's estranged mother in an ad left Republicans in Ohio and Washington reeling on Wednesday, as both Ramaswamy and Vice President J.D. Vance doubled down on the divisive strategy.Publicly, Republicans were mounting a defense, led by Vance, who is from Ohio and was campaigning in Cincinnati on Wednesday, treating the ad as a gamechanging October surprise. But privately, old-guard Republicans were baffled that Ramaswamy would dare to deploy Democratic nominee Amy Acton’s own mother, who has not spoken to her daughter since 1978 when she defended Acton’s stepfather who was indicted for raping Acton as a child. Some predicted the ad was likely to draw more empathy and interest in Acton from voters, and turn them away from Ramaswamy. “We’ve lost the plot,” says one Republican strategist. “We had a real good chance and then we do this two weeks out.”Adds a second: “We now deserve to lose this race.”The addition of this ad so close to Election Day roiled races in Ohio up and down the ballot. “I would not have run that ad,” Republican Sen. Jon Husted, running in a tight and expensive race for re-election against Sherrod Brown in Ohio, told The Associated Press on Wednesday. Other players in the state's Republican circles say the ad has all the pieces of a misfire, especially among women.Recent polls have shown Acton leading but not running away with the race. A Marist University poll released this week showed her up seven points. But Ohio is a state where President Donald Trump won three times, never with fewer than eight points to spare. If elected, Acton would be the first Democrat to become Governor since 2007.Ramaswamy’s campaign said it was putting $4 million into making sure the ad gets seen, with a goal of targeting persuadable voters still undecided between the billionaire entrepreneur and Acton, the former state health chief who steered Ohio through the pandemic. But the risk of it backfiring is incredibly high with no time to recover.Ramaswamy’s campaign includes several operatives who previously worked for Vance, who sidestepped questions about the ad’s message on Wednesday as he urged Republicans to not allow such hard-nosed messaging to distract them from the stakes of the election. “I’m a little bit disgusted when I see Republicans across the country who are whining more about that advertisement than they are about what the congressional Democrats and other Democrats want to do to the United States of America,” he told reporters. “So I would say to Ohio Republicans: do you actually think that Amy Acton is unfit to serve as Governor of the state of Ohio? I do.”By Wednesday afternoon, it was clear Vance might be in a decided minority. “I don’t have to agree with Amy Acton’s politics to believe that exploiting someone’s childhood trauma is wrong,” wrote Republican Lydia Mihalik, a member of Ohio Gov. Mike DeWine’s Cabinet. Mike Murphy, a strategist who was in Sen. John McCain’s inner circle when he ran for President in 2000 and headed Gov. Jeb Bush’s super PAC in 2016, wrote a brutal assessment on social media, saying it “is looking more and more like political suicide.”And former South Carolina Gov. Nikki Haley, who ran against Ramaswamy in the 2020 presidential primaries and was a frequent critic of him, was even more direct. “He’s a bad guy,” she said. “It’s a shame he continues to get away with it.”In an editorial endorsement of Acton published Wednesday, The Columbus Dispatch roundly condemned the video: “It should go without saying that sexual violence against children should not be politicized or taken as lightly as Ramaswamy appears to take it.”For its part, Acton’s campaign began an ad of its own calling out Ramaswamy’s effort to make her childhood a campaign issue after a half century in the past. "I received a lot of abuse, but Amy always got the worst of it,” Acton’s brother, Phil Stearns, says in a new 30-second ad released Wednesday. “She continued to receive that abuse because she knew she had to protect me from that, and if she hadn't done that, who knows where I would have ended up.” "She was 11- and 12-years-old, and to think that that's somehow a talking point—shame on Vivek,” Stearns continues. “The contempt he has for Amy is the contempt he has for Ohio. He's not fit to lead."
