Senator/Former-First-Lady isn't part of "Washington Establishment" ???

I read David Sirota's blog from time to time. He's much less crazy/volatile than Kos and his Kossacks, and Sirota usually has some intriguing and on-point things to say.

Sometimes, he says things like this (on his blog here):

Sen. Hillary Clinton (D-NY) today said that, unlike some other senior Democrats, she is going to support the will of Democratic primary voters, and support the winner of the Democratic Party primary in Connecticut between turncoat Sen. Joe Lieberman (R-CT) and challenger Ned Lamont (D-CT). She should get a lot of credit for coming out and making this announcement. Yes, I know - it is a pretty low bar to give Democratic Senators credit for saying they will support the Democratic Party Senate nominees. But the dynamic of this race is shaping up to be the Washington Establishment vs. The Rest of Us and Clinton is firmly taking the side of The Rest of Us. That’s a good thing, and a major step forward for her. She should be applauded and, moving forward, she should be encouraged to continue in this kind of direction in other policy areas.

Read it and notice this bizarre sentence: "But the dynamic of this race is shaping up to be the Washington Establishment vs. The Rest of Us and Clinton is firmly taking the side of The Rest of Us." (emphasis and italacs are obviously mine)

Apparently, Sirota believes that Senator Clinton isn't acting as part of the Washington Establishment when she says I'm only supporting nominated Democrats. Even though she's been active in her husband's political life for many years, even though she was First Lady for eight years, even though she's been the junior senator from New York for six years now and she wants to keep that job.... She says she won't support Senator Lieberman if he fails to win the Democratic primary race, and suddenly she's part of The Rest of Us????

Sorry, David, but that's like saying "W" campaigned in 2000 as a political outsider. It just doesn't make any sense.
