Washington (CNN) – It's the biggest headline in a national poll full of headlines: Newt Gingrich has surged and is now basically tied with Mitt Romney in the race for the GOP presidential nomination.
According to a CNN/ORC International Poll released Monday, 24% of Republicans and independents who lean towards the GOP say Romney is their most likely choice for their party's presidential nominee with Gingrich at 22%. Romney's 2-point advantage is well within the survey's sampling error.
While the level of support has pretty much stayed the same for Romney, the former Massachusetts governor who's making his second bid for the White House, the former House speaker has seen his support jump 14 points since October.
"It's better than when I was at four [percent]," Gingrich said Monday on the campaign trail in Iowa.
But he cautions that anything could happen, saying that "this is the most volatile race of my lifetime."
