DeteNews.com, MI 10-11-07 Giuliani, Romney continue debating The two snarl over use of military force on Iran; the former governor campaigns Wednesday in Royal Oak. Gordon Trowbridge, Detroit News Washington Bureau ROYAL OAK -- The jousting between Republican presidential candidates Mitt Romney and Rudy Giuliani continued Wednesday, as each bashed the other over comments made during Tuesday's debate in Dearborn. The pair -- who sit atop polls in Michigan and other early-voting states -- sparred during the debate over taxes and spending, an issue of increasing contention between them leading up to Tuesday's event. On Wednesday, the topic was military force, with Giuliani's campaign attacking Romney for suggesting he would consult lawyers before launching an attack on Iranian nuclear sites. The Giuliani-Romney scramble took some of the spotlight from the story on the Democratic side, where four top Democrats removed their name from Michigan's ballot on Tuesday. Those decisions seemed to have pushed Gov. Jennifer Granholm toward endorsing Hillary Clinton, the only top contender still on the ballot here. Granholm has widely been seen as likely to endorse Clinton, but she came close to doing so Wednesday. "I'll be announcing on an endorsement next week," Granholm told reporters. Asked if she would endorse Clinton, the governor said: "Suffice it to say I'm very disappointed in the candidates who have chosen to back out." John Edwards, Barack Obama, Bill Richardson and Joe Biden all have removed their name from the ballot. Dennis Kucinich announced Tuesday he had done the same, but the Secretary of State in Lansing said the campaign had filed incorrect paperwork and missed the 4 p.m. Tuesday deadline to withdraw. The Giuliani campaign jumped on Romney's answer during Tuesday's debate to a question on attacking Iran. "You sit down with your attorneys, and they tell you what you have to do, but obviously the president of the United States has to do what's in the best interest of the United States to protect us against a potential threat," said the former Massachusetts governor and Michigan native. Giuliani's campaign sought to compare the answer to John Kerry's comment during the 2004 race that U.S. military action should pass a "global test" -- which Republicans portrayed as giving other countries veto power over U.S. action. Speaking to reporters outside a Royal Oak diner, where he campaigned Wednesday, Romney fired back, calling the issue "phony" and rapping Giuliani for his own reliance on lawyers. "He gets first place when it comes to suing and lawyering," Romney said, criticizing the former New York mayor for suing the federal government to overturn a line-item veto law, taxing commuters and filing other lawsuits during his time as governor. Giuliani argued Tuesday night that the line-item veto over which New York sued the Clinton administration was, in fact, unconstitutional. "Hopefully, Mitt Romney isn't going to check with the same group of lawyers who told him the Bill Clinton line-item veto was constitutional," Giuliani communications director Katie Levinson said Wednesday. The nomination fight increasingly has centered on the sparring between Romney and Giuliani, and Romney showed no sign of slowing his criticisms. "The contrast between my position and Mayor Giuliani is so stark that the opportunities for discussing those differences is something the campaign is going to see more and more of," Romney said. For both candidates, there is a tactical advantage in the exchange, said Steffen Schmidt, a political scientist at Iowa State University. "It's a declaration of victory," Schmidt said. "It says, 'We are the top two.' And it works." Staff writer Mark Hornbeck contributed to this report. You can reach Gordon Trowbridge at (202) 662-8738 or gtrowbridge@detnews.com.
