When the IRS was stupid enough to target people based on their political beliefs - - tea party members - democrats had the IRS 'investigated' by the same folks who had found that a film director caused Benghazi...
The 'investigation' showed nothing.
What would happen if Iranians fired on a US vessel and Obama told our navy NOT to fire back?
Really. My guess is NOTHING.
Just like Benghazi. Just like conservatives being targeted by the IRS. Nothing would happen. The press would cover it up and call anyone who objected an 'extremist'... and the discussion would go back to 'immigration'.
