It's also wishful thinking to suppose a corrupt, weak Congress would ever do anything to limit their own corruption. John McCain discovered there was zero appetite for reform.

It would take the sustained, coordinated efforts of many ~millions of people to peacefully* overthrow and reform a system which is entirely corrupt and unwilling to work for anyone not rich/powerful. Instead, at present, American voters are far too uninformed, uneducated, divided-and-conquered and/or demoralized in red/blue team bullshit factions to clearly characterize the situation they are in and the most correct response(s) to it. There will be no "progressive resurgence" through political means, but there could be corporate James Carville->Ezra Klein pseudo-progressive swing to the pretend, corporate left fronted by another wife cheater, Republican Lite (tm) like Gavin Newsom. Nothing will change.

* Those with the power will abuse it and direct illegality towards their enemies just like every dictator does. The hope is that extreme, excessive measures taken against peaceful people weakens their pillars of support. It doesn't always as in the cases of the Bonus Army, Occupy, or about 90% of peasant uprisings. Viet Nam and Gaza Hostage protests similarly also weren't effective enough.
