At home, meanwhile, Harman’s district has changed. In the ’90s, she represented the one L.A.-area district that was evenly balanced between Democrats and Republicans, and her centrist politics were probably the only kind that could have prevailed in elections. But the district was reshaped in the 2002 reapportionment into a solidly liberal, Democratic seat — and Harman’s politics and occasionally bizarre votes (she was one of just two House Democrats to back the administration’s efforts to monitor the records of public libraries when the Patriot Act came up for reauthorization) are now out of sync with many of her constituents. Winograd lacks the resources to mount a serious conventional challenge, but in this year of voter discontent, Harman now has to battle on both coasts.
