I agree with Tomasky that Bernie is a punish-the-malefactors type. That's why the DUmmies love him. That worldview is vindictive, small-minded, and short-sided. What does the punishment actually accomplish, besides making an evil person feel good? Get rid of Snyder, then what? It's the first thing that came to Methuseleh's mind.
Reminds me of a president of a company I once knew. If the sky wasn't blue enough, he'd fire someone just for the fun of it. Never made the sky bluer. Eventually, the dude was fired himself.
