I agree to a certain extent. I was concerned from the beginning about the fact that Rand's campaign decided to ignore the old voters completely. I said before that we needed a super PAC to help Rand with those voters.
Old people seem to vote for the perceived front runner or who they're told to vote for by media coverage. I'm not sure there is a good solution for the liberty movement getting attention from older demographics unless for some reason some day the media were to actually cover us fairly.
