Progressive/insurgent Democrats did better than I expected them to tonight, but that might have been my error in underestimating that wing of the party's strength. So I'd say that's one area where I updated my priors. But I don't think we should move wildly in the "Democrats Have a tea party!" direction because of tonight. We might see something on par with what the GOP saw in 2010/2012, but we're definitely not there yet.
