The 2010 electorate has swallowed an emetic — disgorging in a series of retching convulsions officeholders in both parties who seem to embody conventional Washington politics.

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.

I've said it before and I'll say it again: the 2010 US mid-term elections are all about anti-incumbency. The Democrats will lose the most because they have the most incumbents, but it's not an anti-Democrat election. Voters are sick of the Republicans as well.
