It was when Obama and his attitude, his hatred of the people, was unmasked for all to see. A lot of people had their eyes opened then. It was overkill.
It was exactly as you say. It was obvious to all who chose to see.
This should have been exploited POLITICALLY to the max by the GOPe. However, the GOPe was too timid. They hid from controversy, preferring to enjoy the perks of their positions rather than risk discomfort by taking any risks.
They squandered the political opportunity of a lifetime.
