NRA knows its position is weak, if not untenable.

I've said for a long time that the weaker a position is, or someone thinks their position is weak, the harder it is foe someone to defend it. So when someone is quiet about their position when they are being questioned about it, you can be fairly sure that they believe their position is untenable. This proved correct in 2010 with the Affordable Health Care, as Democrats didn't believe they could win on the facts, ran away from the bill. This was proved again in the 2012 election, as the GOP ran away from candidates who spouted the party line, knowing it wasn't what American wanted. And now the NRA is clamming up, sending no representatives from their organization to the Sunday shows to voice their opinion on actions to attempt to cut down on massacres like last Friday. This shows they know their position is unacceptable to a majority of the American people. A couple of elected officials with strong ties to the NRA tried to explain that one more gun in the right hands would have stopped the carnage. This is the NRA answer after all such tragedies, and it rang just as hollow over the weekend as it had in the past. And that's why NRA officials themselves didn't go on the shows. They know their position is weak at best, and very probably completely untenable to the American people.
