Hard counts, hard counts, hard counts
Now THIS guy gets it:
"The Iowa Democratic Party charged each camp $65K for the list, knowing they had a monopoly to exploit. There are addresses where there is no longer even a physical house, and there are people who have registered recently who are not on the list. And then, of course, campaign rules allow people to register and even change their party registration on caucus night. So, trying to figure out who is voting when there are names on this list that are stale, and people not on the list who are live and in play, is tricky. No, it's impossible."
