They take an Oath... Will adding more words to the words they are already ignoring make a difference?
Not trying to be obtuse or argumentitive... I’m genuinely interested in making something like this work.
The problem is that they have ignored it because it is not specifically spelled out. The Constitution ratifiers thought that it would be obvious that they intended for Congress to have sole authority to write laws by not giving them the power to delegate their authority. They were wrong in thinking that Congress would restrain itself without a constant reminder.
