Since Republican National Committee chairman Reince Priebus introduced the “Growth and Opportunity Project” in mid-March, the party has proven over and over and over again that it just isn’t ready to change.

The latest example of the GOP being intellectually and politically stuck in the 2012 presidential primaries comes courtesy of one of the stars of those disastrous contests: former Pennsylvania senator Rick Santorum. According to Santorum, the Republican Party’s path to revitalization is not a new round of engagement with women, young voters, and other groups that delivered an electoral landslide to President Barack Obama in November. No, Santorum has a different plan for saving the GOP: defunding Planned Parenthood.

The Raw Story reports that Santorum presented his three-point plan to save the party in a fundraising email over the weekend: mobilizing “pro-family conservatives,” “refuting the lies and half-truths that our detractors in the GOP are spreading about us,” and attacking the women’s’ health care provider.

“[W]e are going to push Republican congressional leaders to defund the monstrosity that is Planned Parenthood,” Santorum wrote. “Too many in the GOP want to ignore the millions of innocent lives that have been extinguished by this vile organization. Defunding Planned Parenthood is a winning issue. The polls prove it.”

In reality, polls prove the exact opposite — Americans oppose cutting the organization’s budget, and there’s reason to believe that Mitt Romney’s insistence on attacking Planned Parenthood cost him dearly on election night — but it comes as no surprise that Santorum, who lost his last general election by 17 points, would ignore the numbers.

But Santorum’s plan could signal a serious problem for the Republican Party. Despite the RNC’s effort to moderate the GOP’s tone with an eye towards the 2016 election, it’s clear that extreme right-wing rhetoric will still play a major role as the party settles on a nominee. In fact, Santorum himself may be the messenger once again.

All of the rebranding efforts in the world — even the NRCC’s nifty new website, which features a BuzzFeed-style “13 Animals That Are Really Bummed About Obamacare” listicle (but almost no mention of the word “Republican”) — won’t make a difference as long as the party is represented by ambassadors like Rick Santorum.
