A recent report of Democratic Rep. Jane Harman’s wiretapped conversation has drawn some criticism and calls for an investigation, but now Harman also appears to face a potential 2010 challenge from the left in California’s 36th District.

Democrat Marcy Winograd said she is collecting donations for a 2010 rematch with Harman.

“The grassroots have been dissatisfied with her record for a long time,” Winograd said. “I think the latest… is just icing on the cake.”
