Sen. Ron Johnson has apparently been exposed as the "simpleton that he is" by Hillary Clinton in the Senate Benghazi hearings (according to a recent letter writer). And this exposure should disqualify him when he comes up for re-election.
Johnson's background is in accounting and business, so the questions and answers he is accustomed to dealing with are probably fairly straightforward and unassuming. Clinton, for her part, is a career lawyer/politician. One who gives the lawyer profession a bad reputation. She is totally adept and in her element at side-stepping tough questions (she never did answer Johnson's question), obfuscating facts and stonewalling investigations.
She is obviously involved along with the administration in trying to cover up the facts of the Benghazi attacks in an apparent attempt to influence the last election. And it seemingly worked. In my opinion, Washington and the country needs more people like Senator Ron Johnson and less like Hillary Clinton. Not the other way around.
