Depends on what you mean by revolution, I guess. I would like a realistic, long-term plan for addressing the systemic inequality Sanders quite rightly speaks out against. If you want to call that a revolution, fine, but I’m pretty sure that’s not what Sanders means, and it’s definitely not what most of his supporters mean.
Sanders thinks that because he raises lots of money and draws big crowds that he’s the harbinger of some long-awaited mobilization of hardcore leftists, and that his election is thus just the first step in the socialist reawakening of America. By believing it, he makes his supporters believe it.
This bothers me for two reasons.
One, it’s a fantasy, and it’s one the left falls for again and again. There is no untapped army of disenchanted masses waiting for the right leader to kick open the door and lead them into the people’s paradise. People who don’t vote are no different, politically, from people who do. There is no evidence suggesting otherwise.
Two, as I said above, the kind of change Bernie is promising — revolutionary or not — takes years of unglamorous, boring organizing, using (and eventually appropriating) existing political institutions and infrastructures. Look at the Reagan “revolution,” which flowered in the early 80s but had its roots in the defeat of Barry Goldwater way back in '64. That’s when the alliance of fiscal conservatives and evangelicals that ended up blunting, and even partially reversing, decades of leftist advances was first formed.
I don’t think Bernie Sanders has any time for work on that scale. His supporters certainly don’t. There is no organizing infrastructure for them to tap into (presuming they wanted to), no comprehensive strategy for instituting what amount to radical changes to the US economy, which even if you agree with them would upend the lives of people at all levels of society. To me, this is not something you can hand-wave away, or excuse by saying, “Well, all politicians over-promise, so I’ll support the one who at least promises all the things I want.”
