McCarthy was absolutely right. We are seeing it now. Communists play the long game very well.Is an extremist like McCarthy what this country needs? I think not.
What this country does not need are extremists on any of the sides because extremists are always out to get the other guy. Extreme conservatives are pretty much one and the same as extreme liberals - they both justify almost anything to get what they want in the name of their cause and all others who disagree are pretty much the enemy. What is their cause - extreme control.
