48% support the impeachment inquiry into the president, while 45% oppose it — the narrowest margin Morning Consult has recorded on the question.

The Nov. 15-17 survey found that 48 percent of voters support the inquiry and 45 percent oppose it, a net drop of 5 percentage points since a Nov. 8-10 poll. At the same time, views about how Democrats are handling the inquiry — which is probing Trump’s alleged pressure on Ukraine to investigate his political rivals in exchange for U.S. security assistance — were statistically unchanged, with 42 percent approving and 46 percent disapproving.

The first week of the House’s public impeachment hearings into President Donald Trump did not move public support for the inquiry in Democrats’ favor, according to a new Morning Consult/Politico poll.

The latest poll, which comes as the investigation enters its second week in the public spotlight, marked the lowest net support for the impeachment inquiry and the largest week-to-week shift in views on the matter since Morning Consult began tracking the issue in early October. Nine current and former officials are set to testify before the House Intelligence Committee this week.

Last week, lawmakers heard public testimony from three officials involved in Ukraine policy: William Taylor, the top U.S. diplomat in Ukraine; State Department official George Kent; and Marie Yovanovitch, the former U.S. ambassador to Ukraine. According to Nielsen, an estimated 13.8 million tuned in for Nov. 13 testimony from Taylor and Kent, while that figure reportedly fell by more than 1 million for Yovanovich’s Nov. 15 appearance.

A quarter of voters in the latest poll said they watched the public hearings live on television — a figure driven largely by those ages 55 and older. Thirty-six percent of voters said they saw clips of the hearings online or on TV, while a third said they did not watch the public hearings at all.

At the same time, 28 percent said they had seen, read or heard “a lot” about Yovanovitch’s testimony, compared with 21 percent who said the same of Taylor’s and Kent’s.
