A new poll shows presidential candidates Al Gore and George W. Bush still the front-runners in Iowa, but their huge leads are narrowing. The Des Moines Register “Iowa Poll” released Sunday shows Al Gore leading Bill Bradley 54 to 32 percent among democrat voters. That’s an eight-point gain for Bradley and a 10 point drop for Gore since the last “Iowa Poll” in June. Maureen Monahan is press secretary for Bradley’s Iowa campaign effort. She says the poll is a good snapshot of the campaign and reflects the hard work they’ve done.Jud Lounsberry, Gore’s Iowa campaign press secretary, downplays the edge Gore seems to enjoy at this point. He says they expect the race to be close and says it could be even closer than the poll shows.In the Republican race, the poll shows George W. Bush in first place with 49 percent. That’s virtually identical to the support shown for Bush in a June poll. Eric Woolson is Bush’s Iowa campaign press secretary, says Bush will continue working hard and they realize there is a lot left to do.Steve Forbes trails Bush at 20 percent in the latest poll, but Forbes doubled the amount of support he had in June’s survey. Bill Dal Col, national campaign manager for Forbes, says the Register’s polling technique may not give an accurate snapshot of the race None of the other G.O.P. candidates garnered more than ten percent — and finished in this order: John McCain with eight percent, Gary Bauer with seven percent, Alan Keyes with five percent, and Orrin Hatch with one percent.
