Aren’t tariffs basically raising taxes like you’re suggesting?
The new tariffs are projected to raise an additional $200B this year for the federal government.

I don’t think the next administration, whichever party ends up winning, will be likely to reverse these tariffs just based on how much revenue they bring in for the federal government.
Reducing spending is of course another different problem altogether.
