Support for Impeachment is Falling

i. An Emerson University survey found a . . . more extreme flip among independents.

In October, independents supported impeachment 48 percent to 35 percent in Emerson’s polling. In the new poll released this week, independents opposed it by a 49 percent to 34 percent margin. In that time, overall support for impeaching Trump swung from 48 percent in favor and 44 percent against to 45 percent in opposition to impeachment and 43 percent in favor.

ii. But perhaps most alarming for Democrats is a new survey of Wisconsin from Marquette University. In Wisconsin, a key swing state in next year’s election, Marquette found that 40 percent supported impeaching Trump and removing him from office, while 53 percent opposed it. In October, before the hearings began, support was at 44 percent and opposition was at 51 percent.

Support for impeachment among Republicans and independents in the survey was mostly steady, but support among Democrats dropped by 7 points.

I've read several polls that contradict the one(s) you cited. It doesn't matter much at this point.

You might not be aware that asking about "impeach" and "impeach and remove from office" would produce different poll results. 

At any rate, the process will continue, and you can jump on the latest fantasy bandwagon that says that the process will actually benefit Trump. I say, let's see.
