I listen to Marketplace, and I always enjoy the odd financial indicators that economists sometimes look at. Like how increased freight comes ahead of good economic news, or how fast food restaurants see increased profits in hard times.

It's hardly scientific, but I feel like I've gotten a good impression of where the enthusiasm is in this election based on campaign bumper sticker sightings. I commute four days a week from Philadelphia to Baltimore. Yes, I know I make Al Gore cry. I feel terrible. The point is, I see about 200 miles of I-95 every day, so my bumper sample group is diverse.

I see dozens of Obama stickers every day, but I can go weeks without seeing a single McCain sticker. To be honest, I can't remember the last time I saw one, and I am looking. In fact, I've seen more Bush Cheney stickers from 2004 than any McCain 2008. Going back to early 2008, I've even seen more stickers for Romney and Guiliani than McCain. McCain might be holding his ground in polls, but the view from my Subaru tells me no one cares about his candidacy.

Have you noticed the same thing where you live?
