Newt Gingrich says his victory in Georgia shows that he has again survived what he calls an "establishment" effort to stop his campaign.

Gingrich's win in his former home state was just his second of the primary season, following a January victory in South Carolina. He's now looking ahead to continuing his campaign tomorrow in Alabama and then Mississippi.

The former House speaker says it's the start of "another chapter" in the race for the GOP nomination.

His supporters who were gathered for a celebration in Atlanta were carrying signs touting Gingrich's pledge to bring gasoline prices down to $2.50 a gallon. Gingrich told them that it's an idea that is "practical, cautious and doable." He says the discovery of new supplies of natural gas brought down the price of that energy source, and that the same thing could happen with oil, once limits on drilling are lifted.

He warned Republicans that if Mitt Romney is the nominee, he won't be able to out-spend an incumbent president. And Gingrich again insisted that he himself is the only candidate who can "decisively" take on President Barack Obama in a debate.
