Donald Trump is still the Republican Presidential front-runner, according to a new national survey.
FOX's Rachel Sutherland reports from Washington:
A new Quinnipiac national poll shows Trump with 39% among likely Republican voters.
Marco Rubio is gaining steam, now in second place with 19% support and telling FOX News:
(Rubio) "Our numbers continue to grow and we feel good about what that's going to mean on Saturday night."
Jeb Bush, who has 4% support in the national poll, is staying positive:
(Bush) "We're making great progress, steady progress."
The Quinnipiac poll shows a majority of Republican voters think Trump has a good chance of winning in November.
