>She definitely exploits it to the fullest extent.

As any politician who actually cares about governing should! You don't get to choose the rules in the middle of the game.

If a team is playing Golden State, and they're tired of giving up so many 3 pointers, they can't just come out and say: "The 3-point rule is unfair. We're gonna stop shooting them ourselves to try to shame Curry into stopping." That's not winning, that's surrender. And in politics, winning is a precondition for everything else.

>Bernie opposes this in principal and practice.

And if he continued that opposition in a general election, he would lose. And as a result, all the issues he cares about, including campaign finance reform, would be set back.
