Nobody seems to have mentioned this, but last night Rachel Maddow had a comparative graph of the conservative campaign financing groups showing "bang for the buck" - how much of the money conservative groups gave to winning candidates.
As you can imagine (quite gleefully) every single one got pretty dismal results, none more than 33% effective, as I remember.
However the NRA was particularly dismal in this respect with only 0.82% of their contributions going to campaigns which were actually winners.
I say again: 0.82% effective contributions.
This is the "juggernaut" that Congress is terrified of?????????????????????
