Newt Gingrich began running an ad that debuted last week on his plan to bring gas prices down to $2.50 per gallon in Tennessee. Polls show a three-way race in Tennessee, where Romney, Santorum, or Gingrich could win. A poll Sunday by We Ask America gave Romney 30% with Santorum and Gingrich tied at 29%.
The ad will run in Tennessee through Super Tuesday and go on air later in the week in Alabama and Mississippi.
