The poll, conducted on Monday and Tuesday, found that 55% of Democrats said that their party leaders should press ahead with impeachment even “if it means a lengthy and expensive process that could weaken their chances of winning the presidency in 2020.”

And even a higher number – 66% of Democrats – agreed that Congress should pursue impeachment, “even if that means they will need to postpone efforts to pass laws that could benefit me.”

Overall, the poll found that support for impeachment remains unchanged overall among all Americans – holding at 45% since last week. But opposition to impeachment dropped by 2 percentage points from last week to 39%.
