Well, she actually LIVED in the White House, met with foreign dignitaries, hosted dinners, traveled with the President, and so on. I believe that First Lady gives her some experience, albeit not what they're making it out to be.
On the other hand, what candidate DOES have the experience that is needed to be President? I don't think anyone in the WORLD does.
I guess the First Lady would know the protocols and what to expect when meeting dignitaries. But she sure isn't privy to what goes on in those cabinet meetings and the face-to-face, hardline talks with leaders of other countries. Good question. Who would be exposed to what the President really faces? Top advisors, Sec'y of State, some Vice Presidents, Senators from Illinois ? ;). Oh, this is sure some fun times to follow politics.
Whoever exalts himself will be humbled, whoever humbles himself will be exalted - Matthew 23:12
