Mark Tapscott discusses term limits as at least a partial solution for pork spending. While I don't know if that would help (and may possibly hurt during the lame duck sessions) reduce the discretionary earmarks that creep onto major appropriations bills, I am a fan of term limits nonetheless. I just want politicians to consider their service as just that: service. Give, and then leave.
My simple formula: 8, 10, 12, 14.
8 years for the President, 10 years for Representatives, 12 years for Senators, and 14 years for all federal judges. (the clock starts over for judges reappointed to a new bench; the clock also starts over, eg, for a Senator who becomes President). I have no rationale for the numbers other than they are reasonable lengths and the formula has a catchiness to it.
