He broke the mold, at this point, you can't use the point you just made against anyone, yes?
He was a state senator and a US senator. Even Abraham Lincoln, the closest we’ve ever come, did have one two-year term as a congressman. And although Grant and Eisenhower never held political office before being elected president, commanding large armies is its own type of executive governmental experience, not to mention their slow progression through the ranks to get there. Just being around generals and admirals constantly during my service I learned a lot.
