I wish I had saved a link to a reply I saw here a month or so ago... one of our members had a chat with a high-level Democratic operative ( not one of the big names, but upon reflection, I remembered him ) after a lecture he'd given, and his contention was "a $1.00 bumper sticker was worth about $25.00 of major media advertising," because it was seen by so many different people.
FYI, and FWIW, on the Georgia coast, I see Bush vs. Kerry stickers and signs at about a 3 to 1 ratio. I am seeing more Kerry, ahem! "stuff" as the election approaches.

I counted again on my drive home today.
8 Bush. 0 Kerry.
