It seems to me that this issue is never going to resonate with the American people until it becomes known that OPapaDoc and especially Hillary were complicit in selling arms to Al Qaeda. The congress cannot really get into that subject because it's top secret, to say nothing of the fact that congress was also probably knowledgeable and some degree complicit.
I think the hope is that this information will become revealed from these investigations, but it will have to be through the back door. Until we get to that point, the low info voters are not going to care.
