I haven't been following Obama's picks for cabinet members. Someone care to update me? I think I saw Hillary was taking one.

I've also heard that people who have cabinet positions can never successfully run for office again after that. Is this true? If so, why? And why would someone like Clinton take the position then? Please give me the short version, as usual, too long and I lose track of where it started...

Which reminds me, this week I've had two people tell me either that since I teach physics I must be really smart, or else that physics is a really hard subject. Both times I replied in complete honesty that I think history is harder. Politics/current events might be even worse since things change so quickly, at least history's over and done with.
