Last night, Bernie Sanders achieved a stunning upset in the Michigan Democratic primary. Many leftists are riding high on the victory, a blow in equal measure to the pundits, the pollsters, and the political class.

I’m one of those leftists. It sucks to lose. I’ve done it more times than I care to remember, and believe me, it’s no picnic. And, as I’ve been saying over and over again, Sanders has a genuine shot.

But lest we get too caught up in the question of delegate counts, which Sanders is still trailing in, we’ve got to remind ourselves that there is a much more important long-term battle going on here. Not merely to gut the Democratic Party, but also to educate, agitate, and organize the body politic.
