Opposition to the House Democrats’ drive to impeach President Trump is growing, as 45 percent of national voters oppose the measure versus 43 percent who support it, according to a poll released Thursday.

The results from the Emerson College survey — which come after several days of open testimony by witnesses organized by Democrats — represent a 6-point swing from Emerson’s October poll released while the House impeachment probe was going on behind closed doors.

At the time, 48 percent of voters supported impeaching the president, compared to 44 percent who opposed.

The biggest swing was among independents, who oppose impeachment now by 49 percent to 34 percent, a reversal from October when they supported impeachment by 48-39.

The poll found that 69 percent of American voters were watching the televised impeachment hearings.

Meanwhile, the president’s support in the Republican primary increased this month to 93 percent against former Massachusetts Gov. Bill Weld and former Illinois Congressman Joe Walsh.

Overall, 48 percent of voters polled approved of the job Trump is doing, while 46 percent disapproved.

The Emerson College poll was conducted from Nov. 17-20 and surveyed 1,092 voters nationally.

Of those polled, nearly 34 percent, or 369 people, were registered Republicans. Roughly 37 percent, or 401 people, were registered Democrats. The poll has a margin of error of 2.9 percentage points.

The Emerson survey is the second one released this week that shows favorable results for Trump.

A Marquette Law School poll released on Wednesday found that just 40 percent of voters in the swing state of Wisconsin thought Trump should be impeached compared to 53 percent who felt he should not.

Similar to the Emerson poll, since the impeachment hearings became public, the number of voters who oppose impeachment have increased since Marquette’s October poll.

The Marquette poll, which interviewed 801 registered Wisconsin voters from Nov. 13-17, has a margin of error of 4.1 percentage points.
