He could if he were President, G-d forbid.
I think the allegation that he is a past member of SDS is false. Maybe someone will prove me wrong.
Democrats are notoroiuos liars. One method to lie and confuse the truth is to load the atmosphere with tons of false and fabricated charges which are outlandish and eaqsily refuted. I suspect this SDS membership inference is just such a campaign tactic. Time will tell, but we need to have proof before we jump at things like this. In the issue of Obama defending the death by neglect of born alive children, we have proof and still the Obamatons (like Ruth5 ... do a user search at FR!) try to twist the truth!
