During the 90's, Dick Morris convinced Bill Clinton to support a welfare-reform bill. There were probably some groups opposed to it and Clinton wasn't enthusiastic about the bill. However, Morris convinced Clinton to support it.
Obama was in the Illinois state senate at the time and he opposed the bill.
Now all of a sudden, Obama is claiming that he supported the bill and that he had a role in getting it passed. Both of these claims are false.
Now, Obama has made ads claiming credit for the bill.
This is an example of lying about his resume.
Sometimes, there have been scandals when people lie like that. In 2001, a football coach lied about his accomplishments when interviewing for an elite-level head coaching position. It was found out after he was hired and the team was humiliated because of that coach. The coach resigned shortly after having been hired.
A presidential candidate is setting a very bad example for people by lying about his accomplishments. So this is something that people must find out.
