For anyone with kids of a certain age,"Yes We Can" can only mean one thing: The Bob the Builder Show. Which, as good as it may be doesn't deserve to be elevated to a campaign theme.
For me, it's like nails on a chalkboard. Just imagine if Hillary had chosen part of the Barney theme as a campaign slogan instead and you would get the idea.

I beg, plead, whatever I need to do but please get the Obama creative people onto something new. I also think, because of the reference, it takes away important parts of Obama's message.
Please, I don't want to hit the mute button. I want to hear what Obama has to say. But I swear, I'll do it! I will!
