Poll: Newt Gingrich's lead slipping

With the Iowa caucuses are only two weeks away, the latest polling shows Newt Gingrich's status as GOP presidential front-runner is slipping. In a new CNN/ORC international poll, Gingrich and Mitt Romney are now tied for the lead with 28-percent.  Ron Paul is close behind and on the rise, with 14 percent. And trailing behind in the single digits is Michele Bachman, Rick Perry, Rick Santorum and Jon Huntsman.
