I saw an article that Ryan has started running a new ad in his congressional district race. There were some reports a five or six weeks ago that polls showed that race tightening, but I haven't been able to find anything more recent.
And I haven't seen any polling numbers (his district is next to mine). But his challenger, Rob Zerban, is highly competent, is being supported strongly by the DNC, and is running a lot of ads on TV. Even though redistricting slightly tilted the district in the Republican's favor, it is still pretty mixed. Zerban will most likely do better than any previous Dem challenger to Ryan. But, as Zerban says, let's vote against Ryan twice on Election Day.
