Thanks to a 19th century Supreme Court decision, the authority for the civil rights legislation of the 1960s was ultimately found in the Commerce Clause, not the Fourteenth Amendment. The amendment, however, is continuing evidence of the Union’s hateful (to the right) victory in the Civil War. It provides the authority for gay marriage and other claims based on sex and race that are obnoxious to the right. It incorporates the Bill of Rights, another right-wing grievance. It at least arguably makes the debt ceiling unconstitutional. Finally, it makes children of illegal immigrants who are born on American soil American citizens. Nothing could drive the extreme right crazier than that.
If you’re MTG, it has to go. Period.
