I mean, let's be real here there's just as many election deniers if not vastly more 4.5 years later from 2020's election, yourself included.
But to the question, its 5 months in. He had a decent message, its sort of now been lost and the true colours of most politicians show through and the middleclass and below remain destitute.
But its 5 months so there's still ample opportunity for a good term yet, I don't think a huge % would have jumped ship, but certainly potentially enough to flip an election should we go back to November. I watched what happened in Canada in 4 months, Trump drove conservatives hard back to liberal in a very short timeframe, its not hard to think that sentiment might exist in Americans who were on the fence election night swaying them to cast their vote differently. But Canada is hard to use as evidence for my hypothesis because overall Canada is more left.
100% This. 75% or so of BOTH dnc and gop voters will stay with the party line now matter what. its the 25% of people who could flex either direction that decide elections, and trump has until midterms to deliver on jobs, inflation, and immigration to justify his mandate for the latter half of his time in office. otherwise he may be staring down 2 years as a lame duck who gets all of his actions challenged and repealed by the courts and congress.
