When did the American right turn against him?

When he started opposing George W. Bush. Though Soros describes himself as a centrist, he felt that Bush’s responses to the 9/11 terrorist attacks—creating the Department of Homeland Security and invading Afghanistan and Iraq—were steps toward authoritarianism and endless war. He began funding liberal and Democratic groups. Soros says he hopes for a return to bipartisanship in the U.S., and that only Republican extremism pushed him into U.S. politics. “I don’t particularly want to be a Democrat,” he said. But it’s indisputable that he has given consistently to liberals. In 2016 alone, he spent over $18 million on political campaigns affiliated with Democrats.
