You’re asking the right questions. There are many intellectual pygmies who cannot stand to hear a word against Trump, or ponder what you ask.
This isn’t an answer but it’s worth thinking about: If Democrats have such solid control over the election mechanism that they can rig the outcome, why are they working so hard to keep Trump from even getting the nomination?
“…why are they working so hard to keep Trump from even getting the nomination?”
Because he beat them twice. Because he was successful in office in the face of their dirty tricks. Because he is their deadly enemy. Because that is what they do. When they’re done with Trump they’ll slaughter DeSantis. When they’ve cleared the decks of our “saviors” we’re next.
