There is no "smoking gun" because the MSM doesn't want to look for one.
These things don't just pop up out of thin air. The smoking gun is always being hidden. It used to be that a reporter investigated these things, and through diligent pursuit of the story they find the smoking gun.
But not today. Today's MSM buries the smoking gun. They don't expose it.

I really am inclined to go with the thesis that Obama is a figurehead. The same boss or bosses that are telling him what to do, are behind these IRS shenanigans. That’s why Slow Joe was acceptable to the Democrats as a veep. Should Obama bid this mortal coil farewell prematurely, or get impeached and convicted, Slow Joe would do just as well as Barack Obama to be said figurehead.
