"Without the possibility of reelection, he is free to carry out his real priorities with no fear of repercussions. The WORST legislation, appointments, etc always come when our "elected" officially either decide to retire, of face a term limitation, rendering them unaccountable to the electorate." Uh, been there, done that, and it was worse--see Franklin Delano Roosevelt.
Keep term limits on the presidency, and impose them on the Congress, and all state and local elected officials. "Two terms and out!"
