According to Wikipedia **The heart of the slippery slope fallacy lies in abusing the intuitively appreciable transitivity of implication, claiming that A lead to B, B leads to C, C leads to D and so on, until one finally claims that A leads to Z. While this is formally valid when the premises are taken as a given, each of those contingencies needs to be factually established before the relevant conclusion can be drawn. Slippery slope fallacies occur when this is not done — an argument that supports the relevant premises is not fallacious and thus isn’t a slippery slope fallacy.**
PolitiFact has fact-checked various versions of this topic many times, starting with their "2009 Lie of the Year," Sarah Palin's death panels, as well as on others who are not as much in the public eye as Sarah. This topic has also been covered by FactCheck. This particular one was from a video on a website for a candidate by the name of Dan Fanelli who is running against Florida congressman Alan Grayson.
