I don’t know about “contrast”, but here’s your “compare”:
Richard Nixon = Barack Obama
H.R. Haldeman = Rahm Emmanuel
John Mitchell = Eric Holder
G. Gordon Liddy = David Axelrod
John Ehrlichman = Kathryn Ruemmler
Charles Colson = Robert Bauer
In Watergate, Nixon resigned and all the rest of them went to prison.
May the eerie parallels continue!
I wouldn’t expect Mitt Romney to pardon Barack Obama over his crimes.
