Herman Cain: 'Today, I Could Not Support Rick Perry As The Nominee' (VIDEO)

GOP presidential candidate Herman Cain said on CNN Wednesday afternoon that he could not support fellow candidate Rick Perry as the Republican party's nominee.

Citing border security as a key divide, Cain told CNN's Wolf Blitzer, "Today, I could not support Rick Perry as the nominee for a host of reasons. Him being soft on securing the border is one of the reasons.”

Days after defeating Perry in the GOP's Florida straw poll by a significant margin, Cain aimed to distance himself from the Texas governor not just in the polls but also on policy. As noted by The Daily Caller, Cain explained that his immigration stance represents "a basic difference of opinion" with Perry.

“I feel very strongly about the need to secure the border for real, the need to enforce the laws that are already there, the need to promote the path to citizenship that’s already there,” Cain said.

The former CEO of Godfather's Pizza spent the earlier part of Wednesday responding to former Alaska Governor Sarah Palin's comments that his straw poll win has made him "the flavor of the week." Appearing on CBS' "Early Show," Cain brushed off Palin's comment as "not true".

"Primarily, I have a message that's resonating with the American people, the voters," he said.
