Obama altering his positions and other aspects of his personal history

"He passed a law to move people from welfare to work, slashed the rolls by 80 percent."

Here is a discussion about Obama's new ad on welfare reform:

For His Welfare

Barack Obama is championing welfare reform in his new television ad titled "Dignity." The ad says that Obama "passed a law to move people from welfare to work — slashed the rolls by 80 percent."

But the television spot fails to mention that Obama resisted the very welfare reform bill that led to the reduction in the caseload. Back in 1996, President Bill Clinton signed a federal reform bill in an effort to make welfare what he called "a second chance, not a way of life."

But then-Illinois state Senator Obama told the Cleveland Plain Dealer newspaper that year that Mr. Clinton's stance on welfare was "disturbing."

And on May 31, 1997 Obama said on the floor of the Illinois state Senate, "I probably would not have supported the federal legislation."

Here is another discussion of the changes from ABC News:

The shift in Obama's rhetoric on welfare reform has proceeded in stages. When former President Bill Clinton was poised to sign welfare reform while running for re-election in 1996, Obama called it "disturbing." A decade later, as an underdog running for president against Clinton's wife, he spent 2007 avoiding the subject. By the time Obama emerged as the Democratic frontrunner in the spring of 2008, he began leaving the impression that he was for it all along. . . .

"He worked his way through college and Harvard Law." -- This claim is also false.

But "worked his way" through college and law school? The only back-up the campaign provided for this claim was a quote from Obama's book "Dreams from My Father" having to do with a construction job he had one summer while he was in college, and an article mentioning his job as a summer associate one year at a big Chicago law firm. We asked campaign spokesman Tommy Vietor if Obama held jobs during the school year, or other summer jobs, but he said only, "He had the two jobs I told you about." Unless Obama had a good bit more employment than his spokesman was able to describe for us, it's a real stretch to claim he "worked his way" through school.
