ELVING: There is a process for it. It's right there at the end of the Constitution. So the Founding Fathers were at least willing to be edited. They just really made it hard. First, you need to get supermajorities in Congress, two-thirds in both the House and the Senate. And that's an enormous hurdle, especially in the Senate. But even if you get it through Congress, you still need to get your amendment ratified by three-fourths of the states. That's at least 38 states. That has happened only once in the last 40-plus years, and it's a big lift even before you start to talk about the popularity of guns and the power of the NRA.
