I noticed a Barack Obama supporter with an ad banner on her blog. and the first thing I saw was that the senator has a logo. I can't recall the last time I've ever seen a politician with his/her own logo, other than a certain style of letters they use on many of their campaign signs. Then I noticed that it reminded me of something. Pepsi, that is. Obama's logo looks like something Pepsi would have come up with. The actual Barack ad is on the bottom and a version I made with a replacement Pepsi logo is on the top.
Then I did a search and found this blog entry about Obama's Pepsi logo. No luck finding much on Ron Paul and Dr. Pepper, or Bill Richardson and Yoohoo.
I see that Pepsi's current slogan is "Your World Your Pepsi". Not a very good one. I think it is better suited to a cell phone company. Nothing really can match Coca Cola's "I'd Like to Teach the World to Sing". There's a good campaign song for you, Obama.
