"A Stark and Potentially Durable Change in Politics"

So here's Politico on last night's establishment bloodbath:

The anti-establishment, anti-incumbent fevers on display Tuesday are not new. The ideologically charged, grass-roots activists flexing their muscle in this week’s primary showdowns are the same breed as primary voters who four years ago stripped the Democratic nomination away from Sen. Joe Lieberman of Connecticut, who later won as an independent.

What’s now clear, in a way that wasn’t before, is that these results reflect a genuine national phenomenon, not simply isolated spasms in response to single issues or local circumstances.

This is a stark and potentially durable change in politics. The old structures that protected incumbent power are weakening. New structures, from partisan news outlets to online social networks, are giving anti-establishment politicians access to two essential elements of effective campaigns: publicity and financial support.

In effect, the anti-institutional forces that coalesced in recent years now look like an institutional force of their own.

All I have to say is: Good. Been pointing out for years now that the activist wings are more powerful than they know, or that D.C. will admit. Well, now they know. And so does D.C.
