Is Mitt Romney a sure thing to win the Republican nomination?

Former Massachusetts Governor Mitt Romney was the first Republican since 1976 to the first two races competitive presidential candidate to win Tuesday night with his win in New Hampshire.

Analysts are reluctant Romney is a potential candidate for the Republican challenge, and even he admits that he has a big challenge in the coming elections in South Carolina faces.

But subject to the results of the New Hampshire primary field for Romney, so there is no clear second choice. In the primaries in Iowa, Rick Santorum finished in second place behind Romney. In New Hampshire, Ron Paul was the runner-up with Santorum distant fifth place.
