Because national election results in California are pretty much a foregone conclusion, we don't get too much in the way of campaign advertising at this time of year.
I am in Wisconsin at the moment, however, and the airways here are already flooded. The quality of the "discourse" is disgusting. I am not surprised at being appalled at the xenophobic anti-Chinese Koch brothers stuff, but I was also appalled at the xenophobic anti-Chinese stuff being run by Tammy Baldwin. She should know better.
