A group on facebook named
"1,000,000 Strong for Stephen T. Colbert" is up to nearly 1,200,000 in only 12 days, making it the fastest growing group in facebook history. By comparison,"Stop Hillary Clinton: (One Million Strong AGAINST Hillary Clinton)" has about 500,000 members after 9 months, and "Barak Obama (One Million Strong for Barak)" is at 380,000 after 10 months. I'm not sure any of this really means anything considering a fairly large percent of facebook users aren't even old enough to vote.
Update: the Dems have kicked Colbert out of the South Carolina primary, but Facebookers just can't let go.
