Obama Scared of Colbert?

That's what this report is saying:

A member of the executive council of South Carolina’s Democratic party told CNN that he felt pressure to oppose comedian Stephen Colbert’s bid to join the Democratic primary in his home state by prominent supporters of Barack Obama’s campaign. It has been acknowledged by at least two prominent supporters of the Senator’s bid that they made calls to the State Party pleading with them to exclude Colbert’s name from the ballot.
