Joe puts it very well, into a chess analogy:
I think the people that are upset with the NRA support of Harry Reid don’t really understand the trade-offs involved and what the NRA is trying to accomplish. To best support the members, the gun owning people of this country, they have to play a “chess game” where the can never take back a move, the pieces are clouding in smoke, the playing field is shifting, the rules are only partially known and subject to violation by the individual pieces at any time. Try thinking three or four moves ahead under those conditions and see how well you can do. The NRA plays that game very well. They are experts at it. Sometimes when an expert is at work you will be baffled at the moves they make.
