Indeed.
Many argue that Obammie is the worst president ever.
While I give the Kenyan credit for skyrocketing high into 2nd place (and in fact he may well take that # 1 spot), he is still not as bad as LBJ.
Now let's not get too hasty. You've left out the peanut farmer idiot entirely. And let's not forget that we have slick willy to thank for the prostitution of the social securities disabilities benefit and the subterfuge of the actual cost of welfare.
Really, picking a worst president is quite a challenge - although you can be certain he will be a democrap.
