Well it was a pretty typical primary night last night, in Wisconsin and all around.
First, nationally, the tea baggers gained some more momentum in high profile races, which can only mean that general election voters will be turned off by their nefarious right-wing zealotry. Already, Republicans including Karl Rove have written off Delaware, and thus any possibility of regaining a Senate majority. Perhaps that's only a marginal victory for the Democrats, who still have to get their stuff together, but it's a point worth noting--not everyone is drinking Republican tea. The teabaggers have gone so far to the right that they can't appeal to a mainstream electorate.
