These are all valid points.
However, the issues are the cover-up and obstructionism. Illegal weapons trading probably won’t go anywhere (as you pointed out).
The cover-up is obvious. And Clinton is deep in the middle of it. The Benghazi investigation will end her political career.
Obstructionism is the fault of this administration. This will grease the wheels in the F&F and IRS investigations.

Cover up of what? Obstruction of what?
It's not illegal to tell a story your way, as along as you don't lie under oath or order others to do so.
And it's not illegal to use your political friends to slow down or stop your political enemies, especially when stopping them doesn't require much effort.
The Benghazi posse here seem to believe that "if only the people knew about "Obama", this will all turn out right".
The problem is, the people DO know about "Obama", and they re-elected him.
It's a very big problem, and "Benghazi" is not the solution.
