Ironically, it's not just the ineffectuallity of the DOJ (intentional, in that case), it's the ineffectuality of the political competition, the Democratic Party, to hold the GOP accountable. The Dems inability to cash in on these things is so absurd that people just accept it: The Trump administration and GOP are letting a company get away with contaminating baby formula . That should be repeated by the Dems from now…
The Supreme Court gave Trump immunity, stymieing Democratic attempts at holding him accountable for crimes he was accused of in his first presidency. Holding him accountable this time would require some workaround for the Supreme Court.
When the GOP screws up, they should be losing votes and reputation. The Dems have failed to do that.
