James Madison 06/11/1788
Who are the most corrupt members in Parliament? Are they not the inhabitants of small towns and districts? The supporters of liberty are from the great counties. Have we not seen that the representatives of the city of London, who are chosen by such thousands of voters, have continually studied and supported the liberties of the people, and opposed the corruption of the crown? We have seen continually that most of the members in the ministerial majority are drawn from small, circumscribed districts. We may therefore conclude, that our representatives, being chosen by such extensive districts, will be upright and independent. In proportion as we have security against corruption in representatives, we have security against corruption from every other quarter whatsoever.Source:
Prof. Lessig has put together a database (on Tumblr) of every use of the word “corruption” by the Framers, and then referenced it in a SCOTUS amicus brief. Awesome.
