Digby: Purging The Moderates

There they go again:

DETROIT (AP) -- Republican Rep. Joe Schwarz lost his party's nomination Tuesday, falling to a staunchly conservative challenger in a primary race dominated by a struggle over GOP principles that attracted more than $1 million in spending by outside groups.

Schwarz, a moderate who supported abortion rights, was defeated by former state lawmaker Tim Walberg. With 92 percent of precincts reporting, Walberg had 53 percent, or 31,869 votes, to 47 percent for Schwarz, or 28,168 votes.
