Clinton vs Obama, is there a difference between telling a lie and misquoting someone?

GMA did a piece this am about the Clinton/Obama argument during the last debate. The Clintons were accused of misquoting Obama and GMA thought they did. Obama however was proved to be lieing, esp. about his affiliation with Resko. He claimed he only did 5 hours of work for Resko, they proved his ociation was alot more than that. And he said he returned $80,000 to Resko that he contributed to obama's campaign. They asked him about the other $200,000 that Resko donated to obama-he said he didnt know anything about that. Lies, Lies, Lies. Resko saved him $300,000 on the deal he made with him to buy his house. He has been ociated with Resko for 15 years. Obama said in the last 10-15 years, the republicans have come up with all the innovative ideas. The wording on it was changed around to make him look innocent on that one. However it is interesting to note the 15 years ago, Clinton was the president. Obama lies alot, not a good quality for a president.
