Judging from this, it looks like polls don't mean a hell of a lot until much closer to the actual election.

Boston Herald
October 30, 1991
The poll was taken Oct. 20-24 by Maguire Associates of Concord, Mass., and made available to the Herald.
Tsongas of Massachusetts led with 24 percent; with Sen. Bob Kerrey of Nebraska second at 19 percent; Sen. Tom Harkin of Iowa third at 12 percent; three rivals - Virginia Gov. L. Douglas Wilder, Arkansas Gov. Bill Clinton and ex-California Gov. Edmund G. "Jerry" Brown - were in single digits; and 26 percent were undecided.
But when the names of Cuomo and Sen. Bill Bradley of New Jersey were added to the field, Cuomo led with 40 percent, Bradley pulled 15 percent and the current candidates all fell back to single digits - Tsongas to 9 percent, Kerrey to 8 percent.
