Read the god damned Politifact article and look up the studies if you need to.
Your problem is you are unable to distinguish between unsubstantiated opinion and facts when the opinion tells you what you want to hear. When I read these kinds of articles I see mostly opinion and if you really think there are actually facts that I missed you are going to have to explain what you think is a fact (chances are it is not). Simply telling me that I "don't understand" or "didn't read" simply confirms my impression that you are an ideologue that cannot comprehend the notion that reasonable people can look at the same facts and come to different conclusions.
