Then perhaps you can make a citation to what he actually said with sources and in context, please. Madison (in Federalist 50-52) pointed out that the checks and balances within a limited government precluded such despotism. Madison also preferred to leave the decision as to when to remove a legislator up to the people, as I cited in his own words above.
The rest of your post is equally unsupported assertion.
Now to support my notion that tenured legislators have undue influence over citizens represented by less tenured legislators, one only has to look at "No Child Left Behind", ADA, and the recent immigration "reform" bill to understand the Senator Kennedy and the Commonwealth of MassacuTAXES has more influence on my life than my 2nd term and 1st term Senator from Missouri. (And don't get me started on West Virginia)
