Not all the anti-incumbent fervor in Tuesday's primary elections was directed against members of the Republican establishment.
In Washington, D.C. it was the sitting mayor, Adrian Fenty, who appeared to be losing his primary contest to fellow Democrat Vincent Gray, the city council chair.
With 22 percent of the vote counted, Gray had 54 percent of the vote to 45 percent for Fenty.
If Fenty goes on to be defeated, it wouldn't be a surprise. A Washington Post last month showed Gray with a significant lead over Fenty.
A Fenty defeat would be a repudiation of the mayor's closely watched school reform efforts led by controversial superintendent Michelle Rhee who, among other things, antagonized the teacher union with harsh accountability measures meant to improve performance in a long dysfunctional school system.
