If you evaluate 20th century presidents, and you are conservative or libertarian, and yet you think Reagan and Bush were terrible, I'm asking who was good? If you say none, fine, I get that. In these types of discussions, there's a question that needs to be asked: Compared to what?
I find comparisons between real people and real situations compelling. Comparisons between real people and situations, and the idealistic views people hold in their heads, will always leave the folks who had to solve real problems in the real world wanting. Life is a lot messier than it seems in the freshman dorm over beer and pizza.
I submit that my mention of Calvin Coolidge is an appropriate response to this.
