In the wake of the upset in the GOP DE-Sen primary, there's been a lot of chatter about what the Tea Party means, vis-a-vis the Republican Party. One of the most compelling takes, in my opinion, is that the Tea Party represents a decentralized web of Republican supporters, and that decentralization is the cause of much of the intra-TP conflict and the difficulty the Republican establishment has in co-opting that passion and using it to benefit their preferred candidates (See: Grayson, Trey; Castle, Mike).
This isn't a new story, though it may be one the Republicans haven't heard yet. The Democratic Party has already undergone many of these changes. The growth of online communities like DailyKos, Democratic infrastructure like ActBlue, and eventually the Obama wave had a lot of inputs–minority status and the old saw about necessity and invention, frustration among the base and Americans broadly–but the key point is that growth was largely uncoordinated. The rebranding of the DNC is a recognition of that reality, Natalie Foster, the DNC's New Media Director, told TechPresident's Nancy Scola:
It's not just about the DNC anymore. It's about the Democratic Party. [...] This could become that something that any kid could
draw in chalk in front of their house, that any college kid could riff
That was my first thought as well, which is why I was surprised to see Ben Smith snark "this will turn things right around." While we're only a few weeks out from the election, the point of changes like these isn't to tip the scales in pivotal house races, it's to build a party that is tune with the changing tenor of American life. The same could be said of the growth of grassroots fundraising, or the White House's embrace of non-traditional media outlets. (Also, in fairness, Ben picked up Nancy's take.)
To return to my original point, while there may be an equivalence in process between Democrats and Republicans, I don't mean to suggest an equivalence in content. The Republican embrace of Kristolismo over the past two years has radicalized their base in a way that the Democratic resurgence did not. Embracing a base conditioned by years of opportunistic fear-mongering about "socialism," Islam, the deficit and terrorism seems likely to produce legislative outcomes that are significantly less benign than the healthcare reform bill.
