Newt Gingrich said a Gingrich-Hermain Cain ticket would be "a real possibility" if he won the Republican presidential nomination.

Speaking in an interview with Newsmax magazine, in response to the prospect of a Gingrich-Cain ticket or Cain-Gingrich ticket, Gingrich said that was "a real possibility."

Until recently, Cain had jumped to the head of the Republican pack and was leading the Republican primary field. Accusations that the former Godfather's Pizza CEO sexually harassed a number of women while he was president of the National Restaurant Association seem to have pushed Cain's poll numbers down and allowed Gingrich an opening in the front of the field.

A new McClatchy-Marist poll released Wednesday found Gingrich in a near perfect tie with President Obama among registered voters. The poll found that Obama leads the former House Speaker 47 percent to 45 percent.
