There have been a lot of ups and downs in the GOP primary. And speaking on CBS' "The Early Show," Democratic strategist Robert Zimmerman put things into a whole new perspective, saying:

“The Herman Cain surge . . . is a campaign running on political Viagra. His rise is just as temporary and artificial as the Donald Trump, Michele Bachmann and Rick Perry rise."

Stiff words for Cain!
