The new Sept. 24-26 poll of 1,640 registered voters — conducted as House Speaker Nancy Pelosi (D-Calif.) endorsed an impeachment inquiry and details emerged about the president’s pressure on Ukraine — found the public divided at 43 percent on the question of whether Congress should begin proceedings to remove Trump from office, a net swing of 13 percentage points in favor of impeachment since a poll conducted over the weekend. The figure for support rose 7 points, while opposition dropped 6 points.

The latest numbers nearly match an August 2018 poll, conducted as Paul Manafort, Trump’s former campaign chairman, and Michael Cohen, his ex-personal lawyer, were both convicted of crimes stemming from former special counsel Robert Mueller’s Russia investigation. In that poll, 42 percent of voters supported impeachment and 42 percent opposed it. Each of the polls has a 2-point margin of error.

Among those voters who support impeachment now, 59 percent said Trump committed an impeachable offense, a record high since Morning Consult began asking about it in May 2017. The last high was 52 percent, in the August 2018 survey.
