This is a good place to note that neither party -- not Trump's GOP and certainly not the Democrats -- are talking about reducing the power, reach, control, and even ownership of government over individuals, businesses, the economy. It's still statism run amok.
Many of the ways that Musk will be hounded once Dems get power will not involve lawfare (as much as weaponization of the regulatory state and red tape).
But there WILL be lawsuits. And Musk's inability NOT to keep tweeting through it will make them so much worse than otherwise.
