This is interesting.
The latest national poll from Emerson College finds 45 percent oppose impeaching President Trump, against 43 percent who support it. That’s a 6-point swing in support from October, when 48 percent of voters supported impeachment and only 44 percent opposed.
More importantly, the poll shows more independents now oppose impeachment than support it, a significant change from Emerson's polling in October. The new poll found 49 percent oppose impeachment compared to 34 percent who support it. In October, 48 percent of independents polled supported impeachment, against 39 percent who opposed.
