In time, this could make other limits on freedom acceptable.
The author assumes which of the following?
(A) The next presidential election will be dishonest, as has happened in eastern European countries.
(B) The government will soon start curtailing the activities of those it considers “dissidents.”
(C) Blanket restrictions on law-abiding individuals are contrary to the traditions of American culture and law.
