RYE, N.H – Republican New Hampshire Gov. Chris Sununu says he is not calling on his friend Chris Christie to drop out of the GOP presidential nomination race.

However, Sununu tells Fox News that Christie’s “numbers are falling” and argues that the former New Jersey governor has “hit his limit” as he runs a second time for the White House.

Additionally, he emphasized that Christie “has the chance to be the hero. To put Nikki [Haley] over the top. To deliver [former President Donald] Trump that loss, Nikki that win that the rest of the country’s looking for.”

Sununu, a popular Republican governor in the state that holds the first primary in the GOP presidential nominating calendar, endorsed Haley last month, delivering a blow to Christie, who is once again placing all his chips on a strong finish in New Hampshire.
