U.S. - Democrats have made vows to place extreme restrictions on guns, but they keep running into a problem: Many of their ideas can't go into effect because of an early addendum to the Constitution. They're now calling this the "Second Amendment loophole."
"We just want to get guns off the streets," Cory Booker, one of 583 presidential candidates, told the press, "but this Second Amendment loophole makes it so we can't do that. We need to close that loophole."
The way many gun control advocates would like things to work is, if they read in the New York Times about a particular gun model they think is scary--like an AR-15 or a semi-automatic or a glue gun--they could then just go ahead and ban it and start taking it from people. Normally things would work this way with anything else, but thanks to the Second Amendment loophole, they can't just ban guns because they feel like it.
Closing the Second Amendment loophole won't be easy, though, as it will take two-thirds of the states to sign on, a nearly impossible task. This sort of thing has also blocked many other politicians' brilliant plans, something they refer to as the "Federalism loophole."
