He probably didn't. He was polling very well. Very well. Better than his last two elections for a long time. People pretended he couldn't win and I admittedly didn't think they'd do that since that's exactly what happened in 2016.
Simply assuming the election was stolen will be a mistake because that mindset will help Republicans win their next election. The voters wanted an irreparably changed supreme court and Trump functionally immune from prosecution and that's what the voters got.
None of this makes sense anymore. How could people possibly be shocked this time? It happened before under less favorable circumstances.
