What stalling? They could have filed these cases on January 20, 2021 and got the ball rolling. They didn't want to until it appeared Trump was going to run again. Look at all the lefties cursing Merrick Garland for waiting too long. After the 2022 midterms, it really seemed like Trump was done. I was personally hoping they would put their energy into DeSantis, but Trump stubbornly wouldn't back down.
You want to know who to thank for getting the ball rolling on Trump's win? Alvin Bragg. He filed nonsense charges and the American people saw open lawfare at the highest level and started to side with Trump. Trump was "done" after 2022. The elites weaponizing the law against Trump made him into a martyr. Stupid move and it didn't pay off. Dropping the charges now shouldn't save them from severe repercussions. They were only filed to interfere with an election.
