Nobody that was voting for trump before last night's debate is not backing him now. The same goes for most of those that were going to vote for heels-up before the debate. The "undecided's" are a toss-up, IMO - mainly because I think most of them are just waiting to see which way the majority are going before they "decide". As for the moderators, Trump knew he would be treated unfairly by them and said as much leading up to the debate. This is called playing the refs - he knew he would not get fair treatment but everyone with eyes to see and ears to hear saw what was happening - including any would-be future debate moderators.
PDJT went after Kamabla just enough to seed the narrative that she is lying/incompetent and his closing statement was spot on. I think that last night was a bit of "ropa-a-dope" to lure team lefties into a false sense of success and make them want to do another debate. Trump can then go full throttle against her because she "held her own" in the first debate and can't play the victim when Trump goes in for the kill at the next debate...right before the election.
I watched a good video by CSPAN on X with an audience of undecideds. One young woman stood up and said (among other things) that her decision came down to one question - was she better off now or four years ago? Pointed out that we have the rare opportunity to have experienced what both candidates have done while in office. She felt safer and was doing better 4 years ago. She said she realized she cannot base her decision on who she likes better but who did more for the country. She will be voting for Trump!
