Is any question fair game on the presidential campaign trail? Yesterday, Chelsea Clinton was at Butler University in Indianapolis, when she was asked if she thought her mother, senator Hillary Clintons, credibility was damaged by the Monica Lewinsky scandal. Is that an appropriate question? When Chelsea Clinton was asked by a college student if the Lewinsky affair affected her mothers credibility, this is what she said. "I dont think that s any of your business." But many are asking if it is? And if its a fair question to ask? "Its really out of line to ask her daughter that." "I dont think its fair to ask Chelsea." USIs assistant professor of political science agrees. "In my opinion its not really her question to answer you know thats something that happened to her father." Professor W.R. Mack says he believes that personal questions about the presidential candidates in general are tough. Whether its allegations of an affair between republican sen. John McCain and a lobbyist or democratic sen. Barack Obama and his pastors comments. He says the bigger question is not who we should be asking these questions but... "Why are we talking about someones personal life unless it directly effects the decision making that they would have to undertake." The problem says professor Mack is that its been a long campaign season. "It gives a lot of time to look at every nook and cranny of someones life" And with so many media outlets and no clear democratic front runner yet. "Im not saying theyre looking for controversies but sometimes they kinda jump on the thing that seems to be the most controversial and try to milk it for what its worth." What Mack thinks is important is informal forums where people can ask the candidates non-scripted questions. But as far as the Chelsea Clinton question local resident John Campbell had this to say. "I dont think it has anything to do with candidacy. Its just a personal question that she shouldnt have to answer." That college student who asked Chelsea Clinton the question says hes actually a Clinton supporter. He says he was trying to get her to show "what makes Hillary so strong."
