My numbers don't come from FOX, Real Clear Politics and YouGov polls. I think they show reality minus the partisan bias that almost everyone has one way or the other when it comes to Trump. Now you asked about conservatives. On 13 Nov 15% favored impeachment and removal vs 78% who oppose. On 19 Nov, after a week of hearings you have 10% of conservatives who favor impeachment and removal, 81% opposed. After one week the conservative movement has been ever so slightly towards opposition to impeachment.
This I don't find surprising. When something like this happens, first there is a circle your wagons approach. The same thing happened when Bill Clinton was first impeached. Almost all Democrats came to his defense, you're seeing the same thing happening here. You have to give it more time, it is a natural instinct to protect one of your own. The bottom line is after a week of hearings, no opinions have been changed. The slight movement can easily be explained in the polls margin of error of plus or minus 3 points.
What's most interesting to me is the percentage of those who states they watched the hearings or at least some of the hearings. 41% of all Americans said they at least watched some if not all, 59% said none. Broken down via party the percentages were 52% Democrats who watched at lease some if not all, 48% none. Republicans, 44% said they did, 56% say none. Which whether or not in my opinion, no matter what goes on in the hearings, most Democrats and Republicans aren't going to change their minds regardless of the hearings show. It's independents that fascinate me. Independents, the less to non-partisan's, not affiliated with either party, those who are neither pro or anti Trump, the ones who very well could change their minds, only 31% have watched all or some of the hearings, 69% none. So those who could change their minds one way or the other, basically aren't watching. Perhaps not even interested. There reasons for that, but this is too long already to address them.
