The long-shot Republican challenging New York Gov. Andrew Cuomo (D) wants more help from New Jersey Gov. Chris Christie (R), in his role as chairman of the Republican Governors Association.

If he doesn't get it. Well, then maybe Christie should quit, he says.

"Clearly he can come across the bridge and not just raise money for himself, but raise money for the Republican candidate here -- unless he is unable or unwilling because of an issue that we don't know about with Andrew Cuomo and the 'Bridge-gate' scandal," Westchester County Executive Rob Astorino (R) told Fred Dicker Tuesday on WGDJ-AM.

"And if that's the the case and he feels he can't do it," Astorino continued, "then maybe he should step down as chairman."

Christie signaled in Connecticut on Monday that he probably won't be campaigning for Astorino.

“I will spend time in places where we have a chance to win, I said that right from the beginning,” said Christie, according to the Newark Star-Ledger.

A Siena College poll this week showed Cuomo lapping Astorino, 60 percent to 23 percent.

Christie added, “If the New York race becomes competitive, I’ll consider campaigning in the New York race, but right now, by the public polls, there’s a lot more competitive races like this one in Connecticut.”

Astorino said he thinks Christie has done "a good job" in New Jersey. But he said the governor's job as RGA chairman "is to raise support and money for Republican candidates and governors."
