A super PAC trying to boost Ron Paul's candidacy says it will spend $1.4 million on radio and TV ads ahead of the Florida primary.

Endorse Liberty says its goal is to show the Texas congressman is the only GOP candidate who has been consistent in his views.

"We believe that as Florida Republicans learn more about the men running for president, the more they'll come to realize that Ron Paul is the only candidate who shares their core values," the group said in a statement.

Endorse Liberty is one of two political action committees trying to boost Paul. The Texas congressman has acknowledged that Florida will be a tough state for him, given its size, costly media markets and the fact that it will award all of its delegates to the winner of the Jan. 31 primary.

Endorse Liberty garnered attention for its Web ad of featuring impostors posing as Mitt Romney, Newt Gingrich and Rick Santorum. So far, the super PAC has spent more than $3.1 million in the campaign, according to records compiled by the non-partisan Center for Responsive Politics.
