Closing arguments on the campaign trail in New Hampshire.

FOX's Jon Decker reports from Manchester:

With primary day here less than 24 hours away, all of the Republican presidential candidates continue kris-krossing the state trying to win over undecided voters.

Donald Trump continues to hold a dominant lead in most opinion polls. Meanwhile, Marco Rubio appeared to have momentum coming out of Iowa, but that may have been halted by a poor debate performance here on Saturday night.

That has given new life to the struggling candidacies of New Jersey Governor Chris Christie, former Florida governor Jeb Bush and Ohio governor John Kasich, all of whom are touting their executive experience.
