Amending the constitutional is a much higher bar than people think it is. You’d need way more than just a fetterman here or there. Keep in mind still had 38 republicans vote against his and Trump’s second version of the bill

It requires 2/3 of congress, and 3/4 of state legislatures

Assuming he loses zero republicans, this you would need:

67 in the senate meaning you’d need 14 dem senators

290 in the house of representatives meaning you need 70 dem reps

And in state legislatures, he’d need 38 of them to ratify. Republicans only have a trifecta in 23 (it’s unclear if governors can veto ratification or not), they have both state legislatures in 28, and it’s split in Alaska, Michigan, Pennsylvania, and we’ll see about Minnesota with some legal challenges.

If we assume no governor vetos nor any republicans going against it, that’s 28. Then let’s imagine in those split states you convince them all, that’s 33. Keep in mind each state has its own list of people you’d need to convince, not just one person here

Then in the other 5 you’d have to be talking about states with dem trifectas where it’s hardly going to be politically popular to bend to Musk

You would need on the order of at minimum of 100+ dems in congress and state legislatures to pull that off assuming governors don’t veto / ruled that they aren’t able to. And also assuming that all republicans go for it at all levels of government, and that dems in other states with republican legislatures don’t use procedural tactics to slow down ratification, etc.
