One of my readers in California is nervous about the reelection bid of Rep. Dan Lundgren, California Republican. I look at the poll numbers below and see no reason to panic, but perhaps some reasons for concern:

A poll conducted Sept. 18-19 by Public Policy Polling for the liberal blog Daily Kos show GOP incumbent DANLUNGREN with 46%; Democrat AMI BERA with 38%, undecided 16% (MoE +/- 3.9%).
Republican voters: Lungren 78%; Bera 9%; undecided 13%
Democratic voters: Lungren 13%; Bera 74%; undecided 13%
Independent/Other: Lungren 38%; Bera 33%; undecided 29%
Asked if they have a favorable or unfavorable opinion of Dan Lungren: favorable 39%; unfavorable 46%.
Ami Bera: favorable 20%; unfavorable 20%, not sure 60%.
This same poll showed Meg Whitman leading Jerry Brown 50% – 43%; 7% undecided.
Carly Fiorina leads Barbara Boxer 53% – 39%; 7% undecided
Asked if the approve or disapprove of the job performance of Barack Obama, Barbara Boxer and Arnold Schwarzenegger:
Obama: approve 44%; disapprove 53%
Boxer: approve 37%; disapprove 57%
Schwarzenegger: approve 22%; disapprove 67%

My reader notes that any GOP congressman in California who managed to be reelected in 2008 should be fine this year. But that favorable/unfavorable number suggests that Democratic attacks on Lundgren are getting some traction. This is an R+6 district.
