I too agree with much that 8411c says here, except that during Watergate Nixon didn't have the press in his back pocket.
However, besides Issa & Grassley, we should be thanking the following:
John Dodson the courageous ATF agent who brought this out of the light of darkness in the first place.
Dave Codrea and Mike Vanderboegh who have been blogging this for a long time and brought it to Issa & Grassley.
Sharyl Attkisson from CBS who reported on it as well.
And of course, Katie Pavlich
Keep up the good work folks. I believe that if this plays out into November, the better for all freedom loving patriots.
