Half of Americans said they approve of the impeachment inquiry — about the same as the poll found last month. Respondents are also split on whether they think Trump should be impeached and removed from office.

But 65% of Americans say they can’t imagine any information or circumstances during the impeachment inquiry where they might change their minds about their position on impeachment. Just 30% say, yes, it’s possible.

It’s a tangible example of just how locked in most Americans are in their partisan positions, even as nearly a dozen people have either testified or are set to testify in the impeachment inquiry. The poll was conducted Nov. 11-15 — before, during and after the testimonies of the first three witnesses to be called in the inquiry.
