America would be better governed if House elections were replaced by drawing 1000 randomly selected citizens from the census list.
It would also prevent anyone accumulating years of political experience before assuming office, though, which seems like a serious drawback.
Yes, that's a drawback, but it has an upside. It would prevent any representative from having been a politician for years, so they'd be there to represent the people, not to further their political careers.
If you look at Washington as a whole, it seems rather clear to me that the long-serving politicians are more focused on continuing to get elected than they are on actually representing their people.
