Their message of hope unlike Barack's: Bring back Crystal Pepsi

Denver -- They're not preaching Barack Obama's message of hope, but rather one of their own: Bring back Crystal Pepsi.

Let's rewind: Crystal Pepsi was on store shelves for an early time in the 1990s -- but only for a short time.

The clear drink aimed to bring clarity with purity -- being offered as a caffeine-free, clear alternative to regular colas.

Initial sales were promising, but quickly dropped off, just like the product on store shelves.

Some fight for world peace, they fight for consumer satisfaction.
