The uninvited using the forum to get their media shots in -- this one via ABC's The Note blog:
No, their invitations didn’t get lost in the mail. They were never sent.
Though most of the major presidential candidates were offered the chance to speak at a Labor Day forum here with Sen. Jim DeMint, two of the contenders were not. Rick Santorum and Jon Huntsman were left off the roster because they did not meet the polling threshold set by organizers of Monday’s Palmetto Freedom Forum.
Candidates had to reach five percent or above on the Real Clear Politics national polling average, according to the participation criteria set by the American Principles Project, which is organizing Monday’s event. Huntsman is currently hovering just above one percent nationally and Santorum is at two percent.
But in interviews with ABC News on Monday, both candidates sounded less than thrilled about their exclusion.
