Two primary elections in Maryland yesterday featured moderate incumbents - one Republican, one Democratic - getting dumped in favor of more ideologically pure challengers. Rep. Wayne Gilchrist (R) was tossed out with the help of Club for Growth, while the League of Conservation Voters, EMILY's List, and the SEIU worked to unseat Albert Wynn (D). Moderate incumbents, who live in constant fear of losing their jobs, notice this stuff and adjust their behavior accordingly.
Party government. Get used to it.
