The Supreme Court has more power than the other branches because their justices turned the process of judicial review into "the Constitution means whatever the hell we want it to mean." If we get ever get a decent majority of conservative justices on the court, that will result in a return to the proper balance between the branches. No new constitution is needed; the left could ignore the new one just as well as they do the old one.
Hasn’t this drooling, lisping idiot Democrat been taking for 25 minutes now?
Nonsense. Power abhors a vacuum.
Congress is, by design, the most powerful of the three branches. They declare war. They coin money and regulate its value. They make uniform rules for citizenship. They enforce Articles XIII-XVII by appropriate legislation. They create and abolish Federal courts, except the Supreme Court, but they control absolutely what cases the Supreme Court can hear on appeal. They exercise exclusive legislation in all cases whatsoever over DC. They issue letters of marque and reprisal. They suppress insurrections and repel invasions. They make the rules for elections to the House and Senate.
The Supreme Court (and the President) are powerful because Congress has chosen to be weak. And they've chosen to be weak for the worst of reasons - vanity and greed.
Getting elected, even to the House but especially to the Senate is like winning Powerball (except it's a lot easier). Even if the voters kick them out, they keep their salaries and benefits FOR LIFE. That's just if they are not corrupt. The fact that most of them become multimillionaires on $174 000/year while maintaining two residences is the result of gross and odious corruption.
But why then are they weak?
They are weak by choice, because once they ascend to this gold mountain, the very, very worst thing they can imagine is getting kicked out. The bribes, the broads, and the booze all stop and they have to go back home, only have sex with their wives, and maybe even work.
And how do they get kicked out? That's simple, and it's mostly our fault.
The only way, as a practical matter, to get kicked out by the voters is to make a small group of them mad - very mad, in fact. Most voters who vote for Congressmen and Senators have no idea who they are or what they are doing. To turn one of America's zombie voters against their representative or Senator takes a small group of people willing to work tirelessly to propagandize against them.
And how to avoid that horrible fate?
Simple. Don't do anything. Write vague laws that allow nothing and prohibit nothing. Make the Executive Branch create the actual laws through regulation, and make the Courts punish malefactors through expansive construction.
Then, when some farmer loses his land or some Moms are upset abut transgender story hour at the library, you can blame someone else and promise to "fight hard for them" if only you return them to the swamp.
