The whole "the left did it first, and now the right is doing it too" thing is pure nonsense.
Both the "left" and the "right" have been using the same dirty tactics forever.
Politics is the second-oldest profession.
In the last thirty years, the left has dragged American politics to new lows, or at least to lows that had been purged from our system. It started with the insane hatred of Reagan and the pathological drive the democrats had to destroy him and then there is the insanity that grips the left over Bush.
Complete nonsense.
