A poll released Thursday finds 48 percent of voters in Republican House Speaker Paul Ryan’s Wisconsin district want someone new to take his seat.

The poll, conducted by progressive firm Public Policy Polling on behalf of a liberal group opposed to the Speaker, also found that 51 percent disapprove of Ryan’s job performance, while 43 percent approve.

Asked if “If the election for Congress were held today, would you vote to re-elect Republican Paul Ryan, or do you think it’s time for someone new,” 46 percent said they would re-elect Ryan, but 48 percent said it’s time to elect a new representative.

Part of voters’ souring on Ryan may be due to the American Health Care Act, narrowly passed in the House earlier in May. Fifty percent said they disapprove of the bill, while 32 percent approved and 18 percent weren’t sure. Voters were evenly divided on Obamacare: 40 percent approved and 40 percent disapproved, while 19 percent weren’t sure.

Fifty percent of the poll’s respondents said they voted for President Donald Trump, and 38 percent said they had voted for Hillary Clinton.
