Interesting points, let's see:
I don't want to make it about the persons themselves to avoid getting into a personal argument, but I don't think proper separation of powers is appropiately enforced by having too many offices across different branches of government (outside of what seems like necessary exceptions, like the cabinet). As a general rule I strongly believe it is much better to reduce offices than have people in multiple positions, although the last attempt to reduce offices did fail.
Well, "serve" as I understand serves a proper purpose there by avoiding the whole appointed v. elected issue. I suppose it depends on what people think the limit is (having 4 offices to me at least sounds a bit excessive).
That's something I could actually support, as it does provide some necessary oversight. I wonder what the rest of the House thinks of it.
I myself didn't find it necessary, but both the President and Reactionary noted his desire to remain in office as SOS while serving in other office. If the House believes it is necessary to remove the clause, I won't complain.
