I have to agree with Ramesh Ponnuru here. Congressmen take an OATH to uphold the Constitution. They exercise their power of “legislative review” by NOT WRITING OR VOTING FOR BILLS which they think violate the Constitution. If they don’t do this, they shouldn’t be in Congress. If an unconstitutional bill gets by them, the President should veto it because he too takes an oath to uphold the Constitution. And if it goes that far, SCOTUS should strike it down. That way all 3 branches of government get to determine the constitutionality of legislation. The Court just gets the last say.
