Edwards can rest easy - he won't have the challenge of Stephen Colbert's candidacy to overcome on his quest for the South Carolina Democratic nomination. The South Carolina Democratic Party rejected his candidacy voting 13-3, on the basis of his national viability. However, they did approve joke candidates Dennis Kucinich and Mike Gravel.
Because Colbert couldn't afford the $35,000 it costs to get on the Republican ballot, his campaign is over unless he is able to run as an independent.
In national polling for the Democratic nomination, Colbert came in at 2.3%, ahead of Richardson (2.1%), Kucinich (2.1%), and Gravel (>1%). Worth noting that the margin of error on the poll was 5% and that the poll was conducted by a Republican strategy firm - but still....
Check out Colbert's stump speech (via Crooks and Liars):
"Did you know that in Inman South Carolina alone, we produce more peaches than all of Georgia? Our peaches are more numerous than Georgia's! They are more delicious! They are more juiciful! The sugar level is superb! Their fuzziness is unparalleled!"
Kazakstan, greatest country in the world
all other countries are run by little girls
Kazakhstan is number-one exporter of potassium
Other Central Asian countries have inferior potassium
Kazakhstan, greatest country in the world..."
Borat would be the perfect running mate for Stephen Colbert on an independent ticket. I can't imagine what possible combination could better highlight the absurdity of the race for the American Presidency.
