Mickey Kaus gets 5%, ends his California Senate campaign, and concedes.

"I congratulate Senator Boxer on her primary victory. But the results send more than one message.

"I'm a blogger. I spent about $40,000. I had one part-time aide, a recent college grad who was prepping for his LSATs. We had no headquarters, no pollsters, no highly paid strategists and consultants. We had a couple of laptops and an old Volvo. And we still ripped off more than 100,000 votes from a three term incumbent because there is a large group of voters who are dissatisfied with the prevailing dogma of the Democratic party . . . "

UPDATE: Kaus and TNR's Jon Chait have dueling interpretations of the percentages.
