you're right but opponents of trump would have far more ground to stand on anything if they started by saying "well we agree with XYZ that trump wants to do, let's offer other strategies he can try if what hes doing now doesnt work".
Nope. Wholehearted rejection of literally every policy, executive order, layoff, lawsuit, impoundment, appointment that this technofascist wannabe tries to pull. The constitution spells out how he can accomplish his goals, and everything he's trying to do requires an act of congress, and there's been literally nothing. If he's so popular and such a visionary dealmaker, why can't he get literally any actual laws passed through a congress completely controlled by his party?
save your energy for the truly heinous things that trump is going to do (starting with the abrego garcia case, and worse).
then, when you have the time, go read article I section 8 and ask yourself how much stuff that isn't in there congress just decided to start authorizing we do. do that before trotting out constitutionalism arguments -- and then search the constitution for where it says the supreme court should be doing judicial review (I'm not saying it's a bad idea). the constitution is basically meaningless in this country and has been from since the beginning.
