ndira Lakshmanan Fri Mar 28, 12:01 AM ETMarch 28 (Bloomberg) -- Hillary Clinton, accused of exaggerating her experience and reversing policy positions, risks a widening credibility gap that may undermine her bid for the Democratic presidential nomination.ADVERTISEMENTThe New York senator, who this week admitted to misrepresenting the danger she confronted in Bosnia, also has come under fire for allegedly distorting her role in opposing free trade and the war in Iraq, and overstating her involvement in bringing peace to Northern Ireland and health insurance to children.The debate over these and other statements is fueling distrust among voters, according to analysts and recent polls. A Pew Research survey released yesterday showed 30 percent of white Democrats -- a group Clinton needs in order to win the remaining primaries -- regard her as a ``phony,'' twice as many as those who perceive rival Barack Obama that way. In late February, just 7.8 percent of voters surveyed by Pew described her as ``untrustworthy.''``She's either fudged her positions or been downright disingenuous,'' said Dan Gerstein, a Democratic strategist who isn't working for any candidate. ``Any one'' episode ``wouldn't hurt her, but the accumulated weight has turned Democratic voters against her.''Clinton spokesman Jay Carson dismisses questions about her credibility. ``She made a mistake recounting a trip she made as first lady to what was in fact a war zone,'' he said, referring to Bosnia. Voters ``don't ask for perfection, they just want to know that you are working hard for them, and no one works harder than Senator Clinton.''More to MineWhile Obama, 46, an Illinois senator, has also been accused of padding his resume and taking more credit than he deserves, Clinton's longer record offers more material to mine for contradictions. And some observers say she's held to a tougher standard.``We pay more attention to her because we know more about her,'' said Hank Sheinkopf, an unaligned Democratic strategist. ``The Clintons have been part of the daily American soap opera for 20 years.'' By contrast, ``Barack Obama doesn't have enough experience in the Senate to `get him' on things,'' he said.A Bloomberg/Los Angeles Times poll conducted Feb. 21-25 found registered voters thought Senator John McCain, 71, the presumed Republican nominee, ``has more honesty and integrity'' than Clinton by a margin of 45 percent to 31 percent. Obama rated equally with McCain on those qualities.Sheinkopf said Clinton hasn't done any more ``issue switching'' in the campaign than most candidates. ``What is new is the ability to catch it,'' he said. ``You can go online and check stuff instantly. Nobody gets away with anything.''Offering AmmunitionStill, Clinton, 60, has provided ammunition to opponents. She has insisted that she supported weapons inspections, not war, in Iraq in 2002, although she gave speeches that year advocating action against Saddam Hussein before voting to authorize the use of force.Clinton did another turnabout on Jan. 25, 10 days after she won the primary in Michigan, where she was the only major candidate on the ballot. She said both Michigan's and Florida's delegates should count -- even though she had previously agreed they wouldn't because the states had violated party rules.
