New Jersey Gov. Chris Christie says he doesn't have plans to campaign for New York's Republican candidate for governor because he doesn't campaign for candidates he doesn't think can win.


Christie was in Greenwich, Connecticut with GOP candidate Tom Foley on Monday when he was asked whether he planned to spend any time campaigning in New York, where Republican challenger Rob Astorino trails incumbent Democratic Gov. Andrew Cuomo by a large margin in public polls.


Christie, who chairs the Republican Governors Association, said he's repeatedly told candidates he doesn't ``pay for landslides'' and he doesn't ``invest in lost causes.''


He said he's focusing on spending time in places where he thinks he can make a difference.


Astorino's spokeswoman noted other Republican governors have agreed to help his campaign.
