You of course picked the poll that showed what you liked but my comment was about multiple polls out. They do show Trump retaining a lot of republican support but outside of his party it’s pretty ugly. Considering that the Republican Party became all about Trump I guess at this point it shouldn’t be surprising. It would be like a cult turning on its messiah.
I don’t see your reasoning being sound on the capital riot just for the simple fact that Biden had already won. There was nothing Pence could do within the Constitution to prevent that from happening. Trump however sold it as a game changing day for him. His followers believed that somehow Trump could still win because he falsely told them so. And as they stormed and rioted did Trump in anyway act like a decent human being much less a President of our country? No he was mostly silent while Rudy was calling elected officials in an attempt to prolong the certification. To me it’s pretty clear he incited the riot and than tried to use it to get republicans to do what he wanted. Pence at best could have prolonged the certification but that was it. If republicans have had the house though I’m afraid we could have seen a scenario where republicans basically threw out the election and picked the loser to stay in power. Fortunately Pelosi is still majority leader there so that wasn’t possible.
