While true, he also did a very good job in duping the electorate for what he actually had in store for them. He ran on America first, no more wars peace president, that will focus on internal matters like immigration and the economy, and for his MAGA base also the Epstein issue, draining the swamp and all that BS.
The segment of the electorate that matters the most and swings the vote to either party are the independents. If they knew he was lying to this extent, where he would do the complete opposite of what he promised, and go on a rampage around the globe starting fires and threatening everyone with war, there is no way he would've won. Absolutely no one had this kind of war on their bingo card when they voted for him, not even his own MAGA base, despite their continued support for him so far, the majority did not want or expect this foreign adventurism and Epstein cover ups.
The biggest loss will come from the non-affiliated, they are completely opposed to him now. There's no way the Republicans survive the next mid term and presidential elections. The Dems can rerun their weakest candidates in Biden or Kamala again, or the most left wing blue haired nut job and they'd still win right now. That's how much of a hole Trump has dug for his own party. It's going to be a bloodbath, especially with the economy in the toilet.
