the gang that couldn't shoot straight

I don't know where to begin with the metaphorical possibilities:

Vice President Dick Cheney accidentally shot and injured a man during a weekend quail hunting trip in Texas, his spokeswoman said Sunday.

Harry Whittington, 78, was "alert and doing fine" after Cheney sprayed Whittington with shotgun pellets on Saturday at the Armstrong Ranch in south Texas...

No matter what the situation, they have an unerring knack for producing the worst possible outcome.

Tell me how the Christofascist Zombie Brigade (thank you, Marc Maron) makes anyone in this country feel safe. I'd really like to hear that explanation.
