GOP hopefuls fight to be known

As Republicans jockey for position ahead of the 2016 presidential race, the possible front-runners have very little name recognition, including Gov. Chris Christie.

Even the best-known Republican, former Florida Gov. Jeb Bush, is not well-known to a large number of voters.

Christie was able to boost his image a bit and remove some of the Bridgegate stench by campaigning for the Republican Governor's Association.

But still, most voters say they do not know enough about him to have a favorable view.
