Des Moines Register 10-21-06 Last debate key chance to impress Iowa voters Today's gubernatorial event allows freewheeling exchanges By THOMAS BEAUMONT REGISTER STAFF WRITER It's a last chance, a pivotal moment, the beginning of the end. No matter how gubernatorial candidates Jim Nussle and Chet Culver approach today's debate, it marks an opportunity for them to leave a lasting impression in this competitive campaign. The event, scheduled to air live at 1 p.m. on Iowa Public Television, is the final chance for Iowans to judge Culver, a Democrat, and Nussle, a Republican, on the same stage together. Today's debate, the fourth meeting of Culver and Nussle, will allow time for freewheeling exchanges between the candidates, a first for the series that has showcased increasingly pointed exchanges. It also comes with a little more than two weeks left until Nov. 7 and as Culver, Iowa's secretary of state, has established a slim lead over Nussle, an eight-term congressman from Manchester. "Culver can probably afford to take the higher road. He's got a cushion, although it's not huge," said Dianne Bystrom, an Iowa State University professor who has studied the effects of candidate debates. "Nussle has got to be careful. It can really backfire when candidates attack." The campaign to succeed Democratic Gov. Tom Vilsack until recently has been waged largely on traditional partisan issue differences, although Culver and Nussle have been stepping up their criticisms of each other's records and positions during debates and through advertising. Culver, a self-described progressive Democrat, and Nussle, who calls himself a conservative, have stuck to their campaign plans, clashing most on economic and social policy. Nussle and Culver have also run hard-hitting advertisements, criticizing each other's issue positions and policy proposals. But this week, Nussle launched a new offensive, attempting to refocus the race on the issue of who is better qualified to lead and questioning whether Culver has the experience and basic competence to serve as the chief executive of state government. Nussle can afford to stick with the tactic, if his goal is to invigorate voters who already are likely to vote for him, Bystrom and some leading Iowa Republicans said. "It's a very difficult thing to appeal to everybody and solidify your base at the same time," said former Gov. Robert Ray, a Des Moines Republican. "This debate is really another step toward getting the people you need locked in." Debate watchers usually tune in either because they've already made up their minds or to learn more about the candidates, Bystrom said. Few walk away from a debate having decided whom they'll support. Both candidates have raised prodigious amounts of money - more than $13 million between them. Culver has raised more than Nussle in the past two fund-raising periods, but Nussle has collected more since January 2005 and had more on hand, according to reports filed Thursday. Vilsack, who is not seeking a third term, advised Culver to remain poised. "I think he needs to continue to do what he's doing, and that's appear calm, comfortable and collected," said Vilsack, who has a stake in the outcome of the election as a prospective 2008 presidential candidate. The end of the debate season clears the way for the run to Election Day and can have an energizing effect on the campaigns, said Eric Woolson, a longtime Republican communications specialist in Iowa. "You do well in the debate, it really lifts you up and it really (gives) you that shot of energy and adrenaline to move you forward into the last days," said Woolson, communication director for 2002 GOP gubernatorial nominee Doug Gross.
