And "Just" voting stopped Trump in 2020. But because everyone was happy that Trump got voted out nobody cared to fix the underlying problems that got Trump elected in the first place Trump won again in 2024.

Just voting is not enough. You need to hold your politicians accountable and make sure they represent your interest not the interest of corporations. If you just vote in democrats and a democratic president but you let the establishment democrats continue to serve the corporations that vote is meaningless because your material conditions won't improve, discontent will continue growing and eventually someone like Trump will be back in office because they have sweet little lies to whisper into the ears of desperate people who will take it into their hearts and vote accordingly.

The proof is right there, you just refuse to see it.
