Hate to throw water on this idea, but the only polls that matter to politicians are ones of presidential approval in their state or district by LIKELY VOTERS.
The broad populace, which includes the 45% of us that won’t bother to vote in 2020, has been antiTrump/impeachTrump all along. And the fact that 100% of the LVs in California want Trump impeached is entirely uninteresting to Ted Cruz or Lindsey Graham.
And when you burrow down into these numbers, you see what the GOP politicos are seeing — that in most cases, their voters tend not to favor impeachment.
Gotta learn to subset the numbers before you analyze……
