The super PAC supporting Republican presidential contender Marco Rubio is out with a new TV ad in the early voting states of Iowa and New Hampshire, FoxNews.com has learned.
The commercial, issued by Conservative Solutions PAC, focuses on national security-- an issue the Florida senator's supporters believe to be one of his strongest.
But the ad's most compelling argument is only mentioned in passing: a new poll showing he is the only top Republican contender in the large 2016 field that would beat likely Democratic nominee Hillary Clinton in the general election.
In a Wall Street Journal/NBC News poll released Monday, Rubio, who sits in third place among Republican candidates, is the only one who would defeat Clinton in a general election match up, 48 percent to 45 percent.
The narrator in the 30-second commercial, called "Safer", describes Rubio as "the one Republican Hillary hopes she never has to run against."
The Cuban-American Rubio has a 36 percent favorability rating among Latino voters, which is high for a Republican, while Clinton garners 59 percent favorability.
Rubio also pulls more independent voters against the Democratic frontrunner in a hypothetical general election contest: 44 percent to 37 percent for Clinton.
Conservative Solutions PAC spokesman Jeff Sadosky did not reveal specifics of the major ad campaign, but said it is part of a major ad buy that started in December, and will run throughout the early state process.
"Running at significant levels," Sadosky told Foxnews.com.
Conservative Solutions PAC, which raised approximately $20 million earlier this year, released their first wave of ads in November.
