At this stage of the game, I would not require a person to have previously run a business. If the person had a fundamental understanding of Conservatism, that would be enough for me. If the person could articulate the message, that would be better than 99% of our Congresscritters can do today.
As other FReepers have expressed in numerous threads, I don't care for this "qualified" stuff, especially the idea that elected office time is a requirement. The Founders set up a system designed not only to discourage career pols, but one where quite literally, ANYONE could become a Member of Congress, even the president, so long as he complies with the Constitution's age and residence requirements, natural-born for president. It is the reason there is no occupation or education requirement listed. Bugs me no end to have those oh-so-elitists talking-heads determining just who is *good enough* to lead this nation and who is not.
