No expert on US governance but I'm not sure the fault lies in the Constitution but rather, the congressional powers that it has devolved over the years to the Executive, for whatever reason. On the other hand, no amount of division of power will cure one of the legs of the stool sitting on its hands.
Which majority leader? House or Senate?
Re-read the Declaration of Independence. The bar for justifying armed revolt is pretty high. Squabbles over policy ain't in it.
Before one gets to 2A one would think that Congress would use it's funding power and law making powers to strengthen and give effect to the constraints that the constitution already places on the Feds domestically. They've already had one civil war to determine where the line between state and federal power resides. It was highly destructive. It's unfortunate that so many of them don't read, much less learn from, history.
Do you think what is happening now in America are just policy squabbles?
Yes. Examples: lax versus tight immigration enforcement; degrees of tolerance for fraudulent claims on government welfare programs; various sub-themes of identity politics (affirmative action, gender identity); protectionism vs free trade; street crime. The previous administration leaned hard in the directions it wanted to go, and this administration is leaning hard in other directions. State and local governments pull in different directions according to their general Democratic or Republican leanings as well.
"Existing policies". Very little binds one administration to maintain the policies of its predecessor. Which is a "pendulumic swing" - a policy that amounts to nullification of federal law, or one that enforces it?
Congress needs to grow some balls and get a grip on the office of the President.
Which Congress?
One which endorses/directs actions that exceed authorities.
Endorsement: presidents shouldn't exceed their authority, and should enforce all laws.
