What you laid out is basically what I've been thinking for a while. He's giving them silly reasons to freak out so they look batshit insane to any moderate conservatives or independents. Though the nutcases are in the minority, they are extremely loud...and the media will jump on it because they like any sort of conflict...so everyone gets to see the freakshow. All of my conservative friends couldn't believe that anyone would chastise the president for telling kids to stay in school. I heard a lot of "I don't like the guy but you can't berate anyone for encouraging kids to do the right thing." They don't like him but not a single one thinks he's a muslim communist foreigner. They are slowly but surely trying to separate themselves from their lunatic fringe...but it may be too late. Maybe Obama will get them enraged about guns next...make some vague statements about banning handguns or something so they will start frothing at the mouth while he gets some important things taken care of sans obstruction.
Though Obama is clearly playing them and exploiting their over reactionary paranoia, I couldn't say whether he is the best. TBH, I don't know enough about past politicians so say such a thing. But he is good...
