Cain thanks Facebook 'friends' in Web video

The Facebook "friends" of other GOP candidates vary widely.

Former Massachusetts Gov. Mitt Romney has 1,122,682, Minnesota Rep. Michele Bachmann has 461,399 and Texas Gov. Perry had 165,740 "likes" on their presidential campaign Facebook pages as of Thursday morning.

Cain, the former CEO of Godfather's Pizza, said the Facebook number is representative of the upward momentum his campaign is experiencing, including rising poll numbers and a surprise win in Florida's straw poll Saturday.

"Thank you and let's take the 200,000 to the next level. This is Herman Cain. Love ya and I appreciate your support," says Cain in the end of his video message.
