I'm fairly sure that the Secret Service has a world of difference between "some members with dubious views on race" and "people who would Literally Assassinate a Sitting President or President-Elect". Now the project of either the secret service turning into a Praetorian Guard that effectively controls the president or the infiltration by very hard-right types with a bit of a white nationalist/milita streak and the ensuing political fallout when this is discovered is interesting but that's not quite the same.
Also, am I the only person who gets bothered by the "Obama Killed" ideas? I know people like to play with him out of the picture, but is "Having to resign due to a treatable but arduous illness or undiagnosed heart condition that will require him to undertake less strenuous work" or "dying while at home reading from said undiagnosed condition" if you really want to off him"? It's a bit less creepy frankly.
