From the article:

Smith said he was seeking to drop the charges against the president-elect “without prejudice,” which would keep the door open for charges to be brought again in the future.

Unless you’re pretending you can see the future.

Based on what exactly? Can you provide some sources that actually state that they didn’t have enough to charge him until 2.5 years after his crimes occurred? What are you

Based on the order of events. You’re the one claiming they built their case then didn’t do anything until there was just enough time to delay. The burden of proof is on you to support that claim.

I’m arguing that delays wouldn’t have mattered if they had charged him long before he’d already campaigned and won the Republican nomination. He was able to avoid a trial precisely because they waited until this point in time to do anything. Delaying is a common tactic in cases with people like him.

If they charged him before he would still delay. You said it yourself. It doesn’t matter when they charge him. Either way he delays until after the election.

Well I can surely have a case against Trump dismissed as an armchair legal expert, so I guess that makes me equally competent to the best that the DOJ had to offer under Biden and the DNC’s leadership.

You couldn’t even read the article or support your claim that the DOJ waited before charging Trump.
