That's according to Bill Clinton, who signed the legislation back in 1996.
it's not that hard to figure out why the Romney Campaign came up with this one. It is positioned to take advantage of basic Republican fears on Obama-that he is a socialist who wants to hand out money for nothing. It flows right into the Reagan era "welfare queen" concepts that still resonate with Republican voters.
In reallity. The Obama administration was responding to waiver requests from two REPUBLICAN state governments- Utah and Nevada- in crafting the new waivers. The waivers do NOT change the fact that the welfare to work laws still have time limits on them.
politifact.com gives Romney's accusation a "pants on fire" rating. I'll admit that it's wise to consider the source on this one. you might want to stay away from Fox and the huffington Post. chrstian science monitor has a good article.
