The ad from Priorities USA characterizes both Ted CruzRafael (Ted) Edward CruzSasse statement: Trump nominee who spread conspiracy theories has a ‘tinfoil hat’ Coalition of 44 groups calls for passage of drug pricing bill For the sake of our democracy, politicians must stop bickering MORE, who won the state's caucuses Monday night, and runner-up Donald TrumpDonald John TrumpTillerson: Russia already looking to interfere in 2018 midterms Dems pick up deep-red legislative seat in Missouri Speier on Trump's desire for military parade: 'We have a Napoleon in the making' MORE as too radical while implicitly knocking Marco Rubio by not including him as a front-runner. 

The ad ticks through comments by each candidate, including Cruz's calls to repeal ObamaCare and carpet bomb the Islamic State in Iraq and Syria until he finds out whether "sand can glow the dark." Donald Trump's call to ban Muslim immigration and remarks that he could shoot up a street in New York and not lose support are also mentioned. 

"Ted Cruz wants to prosecute and defund Planned Parenthood and his foreign policy plan is nothing short of reckless while Donald Trump thinks he knows more about national security than our generals and wants to ban all Muslims from coming to America," Priorities USA spokesman Justin Barasky said in a statement. 

"These are the frontrunners for the Republican nomination and right-wing special interests are going to do everything they can to ensure one of them becomes president. Hillary Clinton is the only one strong enough to stand up to the GOP frontrunners and that’s one of many reasons she’s going to be the Democratic nominee.”

The web ad is part of a new ad buy by the group targeting New Hampshire, but it was not immediately clear how much the group spent on the new round of buys with just more than a week until the Granite State primary. Priorities USA closed January with $45 million in the bank

Cruz won Monday night's caucuses with 28 percent of the vote compared to Trump's 24 percent. But the ad doesn't mention Rubio, who posted a strong showing for third, at 23 percent, and has been a consistent target of criticism from Clinton allies. 

Clinton squeaked out a tight win over Bernie Sanders on the Democratic side as the results spilled over into early Tuesday morning. With 99 percent of precincts reporting, Clinton leads Sanders by a margin of 50 percent to 49.6 percent.
