If you watch politics long enough you realize that the secret to not being forced to resign is simple: just don’t resign. Obvious? Sure, in a way. But for countless politicians it remains oddly elusive. It’s a sort of Zen Koan of political scandals only revealed in its fullness to those who have spent years or decades meditating on the carnival of political scandals.

I often regret when good politicians fail to grasp this. We now see a bad one — Sen. Bob Menendez of New Jersey — trying to make a go of it. As our proverb makes clear, if Menendez absolutely refuses to resign there’s literally no way to force him. But that may not be as big a deal as it seems. Forcing him to resign may not be necessary.

The simplest alternative is for another candidate to defeat him in a primary. It may not be as hard as it sounds.
