Foundations of GMAT Verbal (5th edition), page 369, problem 2:
I cannot understand why "He can hardly be called a liberal" means "He is a very strong liberal". I read the "hardly" idiom explanation in the same book and, in my opinion, the explanation doesn't clarify it but makes it more complicated. Isn't hardly means not, not at all?
He can hardly be called a liberal, for his voting record belies the beliefs he professes to hold.
(A) He is not really a liberal because he votes in a way that goes against liberalism.
(B) He is a very strong liberal and always supports liberal beliefs with his vote.
(C) He is slightly liberal, and his voting record goes along with his beliefs.
