Elizabeth Warren’s proposed crackdown on the National Rifle Association’s influence in Washington, D.C., has a loophole.

The Massachusetts senator is a longtime critic of lobbying and money in politics, turning her desire for “big, structural change” to “level the playing field” into a rallying cry as she campaigns for the 2020 Democratic presidential nomination. And Warren, 70, often uses the NRA as an example in her pitch to primary voters.
