Former-senator and Christian conservative Rick Santorum has also decided to run for the 2016 presidential nomination, making him the seventh potential candidate for the Republican Party. He's joining the parade of candidates that includes Ted Cruz, Marco Rubio, Rand Paul, Ben Carson, Carly Fiorina and Mike Huckabee.

“I’m ready to do this again,” Santorum told ABC News' Chief Anchor George Stephanopoulos on May 27.

If you're not up-to-date with Santorum's politics, now's your chance to get a refresher for 2016. Maybe he'll be your candidate?

He's a Republican from Pennsylvania.

While Santorum was born in Virginia, he grew up and made his political name in the Keystone state, serving in both the Senate and House of Representatives.

He has a wife.

Rick met Karen Garver, who was a neonatal nurse studying to be an attorney at University of Pittsburgh, while trying to recruit interns for his law firm. They married in 1990 and just celebrated their 25th anniversary. Congrats!

...And 7 kids.

The Santorum brood is seven strong, with four sons and 3 daughters. They did lose one child, who they named Gabriel, shortly after his birth in 1996.

He's run before.

Santorum sought the Republican nomination in 2012 and came in second to the eventual Republican candidate Mitt Romney. He won 11 primaries and caucuses during that race before announcing that he was suspending his campaign to care for his young daughter, who was hospitalized for a genetic condition.

He's anti-abortion and anti-birth control.

Santorum is a prominent figure in the pro-life movement and considers birth control unnatural. However, on the latter, his wife has said he wouldn't rush to take any legal action.

He's against same-sex marriage.

Santorum has been really vocal about how he supports the "protection" of marriage as a heterosexual-only institution.

He's an advocate for special needs kids.

Santorum's daughter Isabella was born with the genetic condition called Edwards Syndrome (or Trisomy 18), which means she was born with an extra 18th chromosome. Since her birth in 2008, Santorum and his wife have been outspoken advocates for the care of children with special needs.

He doesn't believe in climate change or evolution.

Santorum believes that schools should "teach the controversy" on issues that polarizing for the religious and scientific communities, so that creationism can be taught in schools. He has also called climate change "junk science" and a "liberal conspiracy."

He can see the down-side of more people attending college.

Santorum has stated that he believes going to college distances kids from religion. And he's not a fan of that.

He's a devout catholic.

Santorum is very open about how deeply his faith influences his politics.

He reallly hates porn.

In his last campaign, Santorum's "war on pornography" caught a lot of attention in mainstream media and talk show circuits. He believe's the Obama administration has turned a blind eye to the damaging effects of porn.

He's a supporter of the second amendment.

Santorum firmly believes in the right to bear arms. He also supported legislation that protected gun manufacturers from lawsuits when their products were used to commit crimes.

He smoked weed in college, but thinks it's dopey.

In his senate campaign, Santorum said that he experimented with marijuana in college, but that he deeply regrets it. While he's ultimately in favor of protecting State's rights, he is morally opposed to legalizing the drug.

What's his foreign policy like?

Santorum served on the senate's Armed Forces Committee for eight years. He's defended the United States' mission to Afghanistan and supports increases in military spending and promoting American exceptionalism.

He has given back.

During his time in senate, Santorum was supportive of a lot of humanitarian efforts, from fighting HIV/AIDS, assisting low-income families in developing countries and numerous charities that help orphaned and impoverished children. Even Bono thinks he's alright... sort of. There have been questions about the legitimacy of his own charities, though.

And, if all else fails, he's got one foot in Hollywood.

Santorum is the CEO of EchoLight Studios, a faith-based production company. He was the executive producer of the creatively-casted holiday film "The Christmas Candle," starring Samantha Barks (Les Mis) and Susan Boyle (X-Factor.)
