I hope you're right but I remember back to trumps travel. Even though the law said specifically the president has the power to do it, the slimebag Hawaiian judge put a TRO on it anyway, stopping it until the SCOTUS overturned him. Do you really think a lib judge resistance member wouldn't try their luck at this?
A presidential exec order is fair game for the courts, but this is not a presidential exec order. This is how the House and Senate conduct their legislative business and a court has no jurisdiction.
I'm not certain why you don't understand the difference.
