It takes a while to get to it down there in the comments section but, really, it's worth it:
The problem is that lefties are not logical. They want to ban farmers from selling their own wheat, but don't dare have a no-fly list, that's unconstitutional.
Admittedly, a good point since, if I'm debating the efficacy and constitutionality of the no-fly list, the Canadian Wheat Board is the first comparison I'm likely to make. I mean, come on, we're talking no-brainer here.
