Presidental Approval Over The Decades

There is an interesting article over at The Best Article Every Day that plots the approval ratings for US Presidents from Truman to Bush Jr. I wanted to comment on some interesting trends I noticed.

• From Truman to Reagan, every President ends with a much lower rating than they begin, and their replacements always come into office with a higher rating than who they replaced.
• Clinton is the only one to leave office with a higher rating than he entered with.
• Somehow, Clinton's rating climbed when the Lewinski allegations were made and yet dropped when he was cleared of charges. Do we actually want a dirty President?
• Bush is the only one to enter office with a lower approval rating than who he replaced.
