How likely are candidates omitted from the Republican debate roster to still have a chance at Republican nomination?

Fox News released their roster for the first Republican debate earlier today. The roster only includes the 10 top polling GOP presidential candidates, meaning that candidates that didn’t make the cut (Rick Perry, Bobby Jindal, Carly Fiorina, Lindsey Graham, George Pataki, and Jim Gilmore) are only given the chance to debate earlier in the day of the prime-time debate.

Do you think that being left out of the official Republican debate leaves the candidates with little chance of getting Republican presidential nomination?
