It was still stupid and political.
The twisting of McCarthy's gaffe was for the benefit of dishonest, stupid and gullible left wing sheeple like the OP.
McCarthy was responding to claims hat the current crop of repubs were not effectively stopping left wing agendas so he pointed out one result of the Benghazi investigation is that it has hurt HR Haldeman Clinton's poll numbers.
Corrupt media, in the tank for neocon lefties, then intentionally misconstrued the essence of McCarthy's point in order to rile up you gullible, stupid lefty sheeple.
