Vivek Ramaswamy is betting $4 million (£3 million) on a controversial attack ad featuring his Democratic rival Amy Acton's estranged mother, despite a growing backlash that has reached beyond party lines. One conservative commentator has already admitted the controversy changed his mind about voting for the Republican.
Jason Rantz, a conservative radio host appearing on CNN's NewsNight on 20 October, said he would previously have voted for Ramaswamy if he lived in Ohio. After learning the background to the advertisement, however, his position changed dramatically.
