The latest CNN poll in New Hampshire shows Mitt Romney leading the GOP primary pack after last week's debate, leaping from 17% to 28% of the vote. In early April, John McCain and Rudy Giuliani were tied in the lead; they're still tied, but now at 20%. The rest of the pack are all in the single digits.
Some speculate that Romney's familiarity to NH voters, due to his term as the governor of nearby Massachusetts, played a role in the unexpected shift. He also rates as the most likeable, scoring with 32% of those polled, while McCain, who won the New Hampshire Republican primary in 2000, was named most likeable by only 12%. Most electable still goes narrowly to Giuliani. (Read more Mitt Romney stories.)
