Dr. Ben Carson says Republican presidential candidates wouldn't be calling on deceased Supreme Court Justice Antonin Scalia's replacement to be nominated by the next president if a member of their party currently held the White House.

Asked on WRNN 99.5 FM in South Carolina if his fellow candidates would say the same thing about waiting to nominate a new justice if there was a Republican president, Carson replied, "No, they wouldn't."

"But then again, recognize that the two picks that the president has selected are ideologues, so there's really no reason to believe that his next pick wouldn't be an ideologue also," Carson said.

Carson said the Supreme Court has become a "political tool," adding that it might be time to look at term limits for the justices.

"When we enacted that program, the average age of death was 47. And now it's 80. You know, things have changed, so we need to change with them," Carson said.
