Former House speaker Newt Gingrich (R-Ga.) on Sunday said conservative commentator Rush Limbaugh was right to apologize to Sandra Fluke, the Georgetown University law student who he called a “prostitute” and a “slut” for her defense of the Obama administration’s new rules regarding religious-affiliated institutions and contraception coverage.

But the Republican presidential candidate dwelled little on the subject, instead taking aim at Obama for apologizing over the burning of a pile of Korans at Bagram air base in Afghanistan.

“But let’s talk about apologies for a second,” Gingrich said. “I think the president was totally wrong as commander-in-chief to apologize to religious fanatics while our young men are being killed in Afghanistan, and I think it was a disaster of an apology. . . .You have the U.N. commissioner to Afghanistan in essence saying, since the president has admitted the United States is guilty, these people should be tried.”

“Now, I think that is a disastrous position for us,” he added.

With the 10 Super Tuesday states up two days away, Gingrich reiterated that he believes he’s headed toward victory in his home state of Georgia, telling Stephanopoulos that he expects to win the state “by a much, much bigger margin than Romney won Michigan.”

“We’re going to go on,” he said. “We’re competing in Tennessee, in Ohio, in Oklahoma, in a number of other states. We’ll pick up delegates in a number of places. Then I think the following week, we’re going to win Alabama and Mississippi, and we’re going to be very competitive in Kansas.”

The nominating contest as a whole “is going to go on for a good while,” he said.

“Gov. Romney, who’s outspent all the rest of us by multiples, is a front-runner without any question, but I think he’s not a very convincing front-runner, and he’s a long way from having closed out this race,” Gingrich said.

He also criticized former senator Rick Santorum’s (R-Pa.) positions on labor issues and said that “when you get out of the industrial states, I think it gets harder for Rick to put together a majority, so we’ll see how it goes next Tuesday.”
