Because I don't believe they're really blocking anything. They just make us think they are. They put on a show for us. If everyone know the real truth about them, it would be chaos and anarchy, so they manage us by pretending that we have a real 2-party system.
You think that Joe Manchin has suddenly decided to do the right thing? Or Sinema? Look at their voting records. You think Murkowski is really going to stand in the way of something the cabal really wants? Or Collins? McConnell is as dirty as it gets. You don't believe if the billionaires who run this world really wanted something, they couldn't blackmail McConnell? They have before.
If there's a 2024 election (I don't believe there will be) and by a miracle Trump won, they'd do the same thing again: marginalize him, box him in, limit what he does, and undo whatever he accomplished when he's gone. The republicans - let alone the dems - aren't going to let him or anyone else dismantle the deep state. And as long as that exists, we're no closer to having a free, just country. Winning those elections isn't getting us to what we all hope for.
