Sen. Rand Paul (R-Ky.) on Wednesday kept uf his war of words with New Jersey Gov. Chris Christie (R), accusing Christie of winning a landslide reelection bid last week because he got federal aid for the state after superstorm Sandy.

"His victory was, in large form, based on that he got a lot of federal money for his state," Paul told Philadelphia radio host Dom Giordano. "Unlimited spending is sort of -- you could call it moderate, or even liberal, to think that there’s an unlimited amount of money, even for good causes."

Paul repeated his criticism from last week that Sandy aid was used to run ads featuring Christie, suggesting the money was used for political purposes, and said that people like Christie were saying they wanted the money with no questions asked.

"If you’re a conservative Republican, the federal government will be involved in certain things. But when you spend money -- particularly when you’re a trillion dollars in the hole, it shouldn’t be just this ‘gimme, gimme, gimme all my money’ without any considerations or strings," Paul said. “It should be, yes, this is why it’s necessary, but this is also why I'll cut spending somewhere else."

Both men are considered top contenders for the GOP presidential nomination in 2016. Christie has criticized Paul and other libertarian-leaning politicians for opposing National Security Agency surveillance programs.
