Because the Republican Party, with Trump as its de facto leader, can't win in a democracy. We saw it with the 2022 election. When people have the opportunity to understand the issues and vote based on their own self-interests, they vote for Democrats. It's only when they are lied to and manipulated into believing the Republican Party is capable of governing and will honor their Constitutional rights (neither of which is currently true) that they vote Republican. That's not always been true--before Trump Republicans were more conservative but still believed in democracy. Not anymore.
