(CNN) - Would Herman Cain ever accept a VP spot on a Romney ticket?
"I'm not saying 'no.' But it's not an automatic 'yes'," the Republican presidential candidate and former CEO of Godfather's Pizza said during an interview on CNN's "American Morning."
He said the decision to run as a vice presidential candidate would depend largely on who it is and "upon the understanding that we could reach about how they saw my role."
But Cain also made clear his goal was to become President of the United States.
"I'm in it to win it."
Cain also took on his opponents for piling on criticism of his "9-9-9 plan" during CNN's debate in Las Vegas on Tuesday night saying he's been trying to be the "likeable guy," but his opponents are "getting on my last nerve".
So what can we expect from Herman Cain in the next debate?
"I'm going on the attack."
