Governing isn't about climbing the ladder and building celebrity status to further one's own ends but about public service. They should have plenty experience *before* reaching congress and then remain largely unknown to other states (who can't vote for them as senator but could as president) by the time they're done.
At least, i would like to try this. Give the senators as little incentive to screw the people, like they just did with college loan rates, to enrich their campaign contributors (they won't have any!) or to appease certain voter demographics (they won't have any!)
