A nice pipe dream would be elimating gerry-mandering. Just draw districts by geographical lines, and let the chips fall where they may. The tax code reduced to a simple fair tax/flat tax would eliminate a lot of problems as well. Term limits for me is an imposition I could reluctantly support, but might not be needed with the above mentioned reforms, which of course will never happen.
I have mixed feelings about term limits. Clearly there are good people that we need to keep. I would go for a two term limit in the Senate and 10 years in the house. Term limits is not the answer, but it would help.
