Counting Nixon, this is the 3rd impeachment in the last half century while there was only 1 before. Why? Elementary my dear Watson. It's the televised era. the era in which every household has a TV.
Poses another question, doesn't it. Is it the TV media which is causing impeachments? Causing division in America? Media was 100% against Nixon. Media won. Media was 100% for Clinton. Media won again. Not only did Clinton stay, his approval ratings soared.
Exactly who (or what) is bringing this Impeachment?
