WASHINGTON -- Here’s where the 2012 Republican presidential candidates stand on the topic of terrorism , including what to do about the detention center at the U.S. Navy base at Guantánamo Bay, Cuba, which today houses 171 captives, four of them convicts.

Minnesota Rep. Michele Bachmann: Expand Guantánamo, no Miranda or constitutional rights for foreign terrorist suspects. “I would be willing to use waterboarding,” now banned, in interrogations.

Former House Speaker Newt Gingrich: Supports extending and strengthening investigative powers of Patriot Act. Supports continued use of Guantánamo Bay detention for suspected terrorists. Supported creation of Homeland Security apparatus, because “we need some capacity to respond to massive events.” In 2009, said of waterboarding: “It’s not something we should do.”

Former Utah Gov. John Huntsman: Said Homeland Security Department has been heavy-handed, conveying a “fortress security mentality that is not American.” Says on interrogations: “We should not torture. Waterboarding is torture.”

Texas Rep. Ron Paul: Opposes the surveillance and search powers of the Patriot Act. Says terrorists would not be motivated to attack America if the U.S. ended its military presence abroad. “The Patriot Act is unpatriotic because it undermines our liberty.” Says: “Waterboarding is torture. And it’s illegal under international law and under our law. It’s also immoral. And it’s also very impractical. There’s no evidence that you really get reliable evidence.”

Texas Gov. Rick Perry: Said it was “unprincipled” for Republicans to vote for creation of the Homeland Security Department. Supports continued use of Guantáanamo Bay detention for suspected terrorists and extension of Patriot Act. Would seek to privatize Transportation Security Administration and decertify its unions. Said U.S. interrogators should “use any technique that they can” short of torture, which he did not define.

Former Massachusetts Gov. Mitt Romney: No constitutional rights for foreign terrorism suspects. In 2007, refused to rule out use of waterboarding to interrogate terrorist suspects. In 2011, his campaign says he does not consider waterboarding to be torture.

Former Pennsylvania Sen. Rick Santorum: Defends creation of Homeland Security Department as an attempt to fix a “complete mess” in the domestic security apparatus. Voted to reauthorize Patriot Act. Says airport screeners should employ profiling; “Muslims would be someone you’d look at, absolutely.” Supports continued use of Guantánamo Bay detention for suspected terrorists. Says waterboarding has proved effective.
