Presidential hopeful Rick Santorum admitted Sunday his race may be approaching its final hour.
He told USA Today and The Des Moines Register, "You reach a point when you realize that you aren't going to accomplish what you're going to accomplish and you have to look out for the greater good."
Yet, he also said he didn't need to win in Iowa to continue his campaign, only to "finish ahead of the pack that's sitting in single digits."
So, is that likely? Ben Carson is the most popular candidate still in single digits. In the latest Fox News poll, he leads Santorum by 6 points. But in the most recent CBS poll, he leads by only 4. (Video via Ben Carson for President 2016)
Beyond Iowa, though, Santorum ranks last in a Real Clear Politics average of statewide polls.
