You're kidding, of course?
This has nothing to do with wrapping up a "drug investigation". It has everything to do with wrapping up Rush.
DAs in South Florida can get take down a score of drug dealers every day. But it's not every day a partisan Democrat DA can become a hero and icon to millions by taking down the biggest Truth Dealer in the country and doing a huge service to his Party.
"Drugs" is the excuse. "Destruction" is the purpose!
Democrats have been looking for a way to get Rush for years, and he knew that. They will stop at nothing to destroy him, and Rush made it all possible.
