Properly speaking, a “dilemma” is a logical situation, not a practical one.
When Hank Paulson had to decide between betraying his ideology with a bailout and risking the collapse of the financial markets by letting Lehman Brothers go down, that wasn’t a dilemma: that was just a tough choice.
A dilemma is a situation in which one of two propositions must be true, and either one wrecks your argument.
Either the nasty stuff about Sarah Palin the McCainiacs are leaking to the press is true, or it is false.
If it’s false, McCain chose a bunch of backstabbing liars to run his campaign.
If it’s true, he chose a greedy, ill-tempered, ignorant vulgarian to be the President of the United States in case of his death or disability.
In either case, McCain wasn’t fit to be President.
