All you have to do is look at all of the impositions that republican administrations and politicians have placed on USPS and the heaps of denigration they've piled on it to see the truth of the matter.
From forcing them to fund all future retirement funding in a way that no other government agency is (the PAEA) to all of the attacks on it around "mail-in vote fraud," to the constant attacks on the budget issues that they created, it's plainly apparent that the Republicans desire USPS failing and being privatized.
Many of them have also literally said as much. AEI and Cato are big proponents of privatization, Trump has talked about it many times, Wells Fargo has created some proposed frameworks, etc., and the worse it performs as a public entity the better they can make the argument for privatization.
