The latest Zogby data:

Pollster John Zogby: “Dean had another good polling day, actually bouncing back to 25 points on Saturday, compared to Kerry’s 28. Undecideds climbed slightly on Saturday, indicating a shift may be taking place.

“Kerry still leads among most sub-groups, including both Congressional Districts, Independents, union members, men, women, and all age groups, but Dean in inching back among 18-29-year-olds, college educated, Democrats, and new voters.

“Dean leads solidly among those ‘very liberal,’ while Kerry is crushing him among Moderates. Two-thirds (66%) of Dean’s supporters say their support is ‘very strong,’ as do 56% of Kerry’s. The race looks as though it is tightening, however, it is Kerry’s to lose at this point.”

Polling results will be released daily through Tuesday, January 27th, the date of New Hampshire’s Democratic primary election. Zogby International conducted telephone interviews of a random sampling of 601 likely primary voters statewide over a rolling three-day period. All calls were made from Zogby International headquarters in Utica, N.Y., from Thursday, January 22 through Saturday, January 24. The margin of error is +/- 4.1 percentage points. Slight weights were added to party, age, education, and gender to more accurately reflect the voting population. Margins of error are higher in sub-groups.
