From Zogby:
“On the Republican side, Mitt Romney, the former governor of Massachusetts, gained a bit on Mike Huckabee, the former governor of Arkansas. Huckabee cumulative three-day tracking total equaled 28% support among likely Republican caucus–goers, while Romney moved up from 25% to 26% support. Arizona Sen. John McCain remained in third place at 12%, tied with former Tennessee Sen. Fred Thompson, who has seen a late-breaking surge.”
Fred comfirmed it, saying his internal polling had him up 4 points in 2 days, but he didn’t give exact numbers.
And from Zogby the day after the quote you cite:
“With a Huckabee surge and a Romney dip, the former Arkansas governor opened up a six-point lead over his nearest rival. Former Tennessee Sen. Fred Thompson also lost a point”
Mostly it’s all just noise, there are so many polls you can pick out selective good points for any candidate. Paul’s ‘surged’ as much as Thompson in the same period, Huckabee was up three points in the last poll, etc, etc.
