> Congress has been effectively gridlocked and do-nothing for at least 35 years--all of my adult life.
Gridlock is a design feature. It literally means there isn't consensus on whatever the topic may be. Do you really want a government that rams through unpopular policies constantly, then 4-6 years later whiplashes back again? What people often express as "congress not doing their job" is in reality "they aren't passing the policies I want!".
> The executive branch's powers are being quickly eroded by SCOTUS.
OP means "restored" instead of "eroded". POTUS was never supposed to be as powerful as they have become. Executive Orders are the worst way to run a country, yet we've had several presidents in a row that have abused EO's to get whatever they want done... only for the next person in office to undo it all with the stroke of a pen.
The only take-away one can have here is we need better civics classes in our schools...
