Or put a life time two term limit on all public offices period.
With no campaign financing or advertising allowed by private individuals or unions , corperations etc. whatsoever, and an elections commission would set up appropriate blocks of air time on the media in equal porportions to the cantidates who passed the political entrance exam in your local area with x number of debates as well as a recorded section on campaig promises and canidates official positions on the issues of note at the time, records and promises for which they could be held accountable later if not met etc by being disbarred from further elections period by popular vote.
I love the idea of part time legislature too, in fact lets only pay each of them 100 dollars for each day in session, and lets cut the hell out of the number of office positions they are allowed as well as eliminate allmost all the amenities that exceed those of a mid-rank officer in the national guard/reserve, why should they get more benifits and make more money than the brave boys and girls who are in the armed services anyway huh?
Or we could take a page from the earliest democracies and select cualified people to office by lot.
