I was talking to a candidate last week in one of the high-profile 2010 races. Campaign coverage has just about evaporated in this candidate's state, I was told, because there are so few reporters left, and those who are still around have bigger priorities, especially this far out from Election Day. As a result, it's hard for the campaigns to get any traction with messages or story lines, and voters are much less engaged.
If coverage is scant for Congressional candidates think about how state legislative or county commissioner races must be fairing? And those have a far more direct impact on the daily lives of the average citizen than Congress does. Just a hunch but I'm guessing that low coverage is good news for incumbents who have built in name recognition.
