If I were a famous American with an 80% approval rating by the public and knew the presidency was mine just for the taking.
I would refuse it.
Being elected after Obama is very much like being made Captain of the Titanic half an hour after it struck the iceberg, or maybe General Paulus being made Field Marshal after he was surrounded by huge numbers of well provisioned Russians in Stalingrad with no hope of being resupplied or evacuated.
Maybe a better example would be being made King of the Persians just before the battle of Arbela.
Is your point that our country is a lost cause and that anyone who would want the presidency is only looking forward to overseeing/implementing our continued destruction?
