Honestly the most realistic path to making it right is to mount enormous election victories going forward. The courts were never ever ever going to overturn the election, no matter what, despite what Steve Bannon says as he asks for more money.
DeSantis has proven in Florida you can clean this stuff up pretty quickly with competent governance. You gotta build real meaninful coalitions nationwide to take this stuff down. You can't have Rona McDaniel as the RNC chair. And you can't have the leader of the party constantly attacking and undermining the successful people in the party. Trump has proven time and time again he just can't get past his own ego... and that's why he continues to fail. He whined about GA in 2020 so we lost the runoffs, single handedly costing us the senate. And then in 2022 we all saw the ****show that came, while he simultaneously attacked RDS and Youngkin and Kemp (2/3 states he lost). Now he's attacking Reynolds and Sununu because they don't kiss the ring.
Trump will never dismantle anything because he's incapable of building any meaningful coalition to allow it to happen state by state. And beyond that, he's also just not smart enough.
