For approximately the past 40 years Republican Presidents have appointed younger Justices than have Democratic Presidents. Depending on how one does the accounting, the average age difference will vary, but will not go away. This Article posits that Republicans appointing younger justices than Democrats may have caused a rightward shift in the Supreme Court. We use computer simulations to show that if the trend continues the rightward shift will likely increase. We also to produce some very rough estimates of the size of the ideological shift, contingent on the size of the age differential. In addition, we show that the Senate’s role in confirming nominated Justices has a significant moderating effect on the shift. Last, we consider the interaction between our results and the oft-proposed 18 year staggered terms for Supreme Court Justices. We show that such an institutional change would almost completely wipe out the ideological effect of one Party appointing younger Justices.
