Scott Adams is voting against Obama because of his administration's crackdown on cannabis dispensaries. He hopes Romney will be better:

Romney is likely to continue the same drug policies as the Obama administration. But he's enough of a chameleon and a pragmatist that one can't be sure. And I'm fairly certain he'd want a second term. He might find it "economical" to use federal resources in other ways than attacking California voters. And he is vocal about promoting states' rights, so he's got political cover for ignoring dispensaries in states where medical marijuana is legal.

So while I don't agree with Romney's positions on most topics, I'm endorsing him for president starting today. I think we need to set a minimum standard for presidential behavior, and jailing American citizens for political gain simply has to be a firing offense no matter how awesome you might be in other ways.

As bad as Obama has been on medical marijuana, Romney would be worse. He wants it all banned, especially the medical part. He sees medical marijuana no differently than marijuana. Look: the man doesn't even drink coffee, because he thinks it's morally wrong. And a pro-pot advocate sees him as a potential savior in four years' time? This kind of purism has been the anti-Prohibition movement's achilles heel. If the above video doesn't convince you of Romney's callousness toward the sick who desperately need medical marijuana to live, there is also this exchange to consider:

Update from a reader:

I agree with you re: Scott Adams, but must ask you to pause on one detail. Do you know for a fact that Romney thinks drinking coffee is "morally wrong"? The fact that he abstains from coffee out of religious observance is not, in itself, evidence of this. As a Jew, I choose not to eat pork or shellfish, but I don't think it's morally wrong to do so. There are a number of reasons why a person may choose to adhere to certain religious practices (tradition, solidarity, a sense of identity, etc). The choice to abstain from a given action is not always a referendum on the morality of that action.
