Poll: 81% of voters say their beliefs on Trump impeachment are mostly set

A Politico/Morning Consult poll released Wednesday found that 81% of voters surveyed said there is no or little chance they will change their minds regarding the House's impeachment inquiry into PresidentTrump.

Why it matters: The poll comes hours before the first public hearing of the impeachment inquiry kicks off.

• A majority of voters (62%) said there was no chance that their views on impeachment would change, and 19% said there was a small chance they could be moved.

The big picture: The new poll found that 50% of voters support the impeachment inquiry and 41% oppose it.

• That's largely unmoved from the last Politico/Morning Consult impeachment poll in October, which had 50% of voters supporting the inquiry and 43% opposing it.
• A plurality of voters (48%) said they "definitely" or "probably" believe that the Trump administration withheld military aid from Ukraine in order to pressure the country’s government into investigating President Trump's political rivals, while 30% said they "definitely" or "probably" don’t believe that.

Between the lines, per Axios' Alayna Treene: House Democrats believe it is imperative that the American people hear directly from the key figures involved in the Ukraine saga in the public hearings.

Methodology: This poll was conducted Nov. 8-10, surveying 1,993 registered voters. It has a margin of error of +/- 2 percentage points.
