On California streets you could almost forget there is a presidential election in less than a month. I saw a car window sticker for "MITT" today and was amazed. I see almost no Obama/Biden materials either. This in a liberal college town, of all places.
There are great advantages of not living in so-called "battleground states." The whole presidential level paraphernalia saying "vote for me" is missing, but not missed.
Everybody takes Wyoming for granted; it will vote Republican. Likewise everybody takes California for granted; it will vote Democratic.
Hence, the only yard signs and billboards are for local candidates: state legislature, city council, county supervisor, and maybe for sheriff. Such folk mostly can't afford TV ads, so we don't see many - how nice.
