In the wake of Sen. Ted Cruz (R-Tex.)'s attack on Donald Trump for "New York values," two of his underdog rivals are now attacking him for ties to Wall Street. In an interview with Time magazine's Zeke Miller, Gov. Chris Christie (R-N.J.) called Cruz hypocritical for bashing the financial capital of the world while building a war chest with hedge fund money.

"Those people have great values, I’m sure, when they are writing him seven- and eight-figure checks," Christie said. "If he really has a problem with New York values, then he should return that money."

And Sen. Rand Paul (R-Ky.), who endorsed Cruz when the Texan ran for his Senate seat, has unveiled one of the campaign's strangest web ads, in which two cartoon figures learn that "the Ted Cruz" is indebted to Wall Street. The video anchors a new micro-site, Audit The Ted, which ostensibly criticizes Cruz for missing a pre-State of the Union vote on Paul's legislation to scrutinize the Federal Reserve.

In animation that resembles the defunct text-to-cartoon site Xtranormal, the new Paul spot begins with a male figure asking "Where does the Ted Cruz get his money?", pronouncing the senator's name with a long "u" sound, as if it rhymes with "fuzz."

"I hear Wall Street money," answers a female figure. "Millions. Even one million from the Goldman Sachs."

"Does the Goldman Sachs want to audit the Fed?" asks the male figure.

"I don't think so," answers the female, who like her counterpart speaks in a British accent. "They are the Fed."

As DIY as they seem, the video and microsite bait Cruz on a topic that has caused quiet consternation with "liberty movement" voters — his wife Heidi's job with Goldman Sachs, and the loans the candidate took out to fund his 2012 race. Paul, who has raised roughly a third as much campaign money as Cruz, is working to make a problem out of his rival's success.
