Were I but King of Anglophonia

As Far As

"As far as presidents, Little Bush is the worst ever."

Can you see that this sentence isn't really complete? It should be, "As far as presidents are concerned, Little Bush is the worst ever."

By itself, as far as doesn't mean anything. If you really are attached to the short but incorrect form of the idiom, try switching to the short but correct forms When it comes to or As for. "When it comes to presidents, Little Bush is not only the worst ever, but the worst conceivable." "As for presidents, Little Bush is so awful that every reference to him as president must make Americans who are religious wonder what awful sin the nation is being punished for."
