Exclusive: Controversial ad backfiring on Ramaswamy, GOP poll finds

Republicans fear that Vivek Ramaswamy 's explosive attack ad featuring his opponent's estranged mother could cost them the Ohio governor's race, based on new internal polling that shows him falling further behind, Axios has learned. Why it matters: The poll's findings underscore Republicans' anxiety over Ramaswamy's decision to air the deeply personal attack on Democrat Amy Acton despite warnings from some fellow Republicans that it crossed a line. Driving the news: The private poll, commissioned by a Republican group and obtained by Axios, found Acton leading Ramaswamy by eight points — up from a two-point lead in the same poll earlier this month, before the ad began circulating on Oct. 19. The ad "is having a significant effect on the gubernatorial race," a memo attached to the poll states. Catch up quick: The ad at the center of the controversy features Donna Arthur, Acton's estranged mother, who accuses her daughter of lying about her childhood and urges Ohioans not to vote for her. Acton has said she was sexually abused by her stepfather when she was 12 and that her mother sided with her abuser. The stepfather was charged with sexual assault but fled to Pennsylvania, where he died in 2004 as a fugitive. Acton and her brother were removed from their mother's custody. Acton has said she hasn't seen her mother since 1978. Zoom out: As Axios first reported , Ramaswamy's campaign treated the ad as a game-changer in the campaign for governor, committing $4 million to airing the commercial statewide despite warnings from other Republicans that it could backfire. Ohio Gov. Mike DeWine (R), who worked closely with Acton when she was the state's health director, said that airing the ad was wrong and urged Ramaswamy to take it down. But President Trump and Vice President Vance backed Ramaswamy. Vance told the bipartisan critics of the ad to "stop whining." The intrigue: The new poll done for Republicans indicates that the ad was indeed a game-changer — just not the type R
