I wasn't being dismissive of the number of people who care about this issue at least somewhat, or enough to say angry things and click on an internet petition. I was, as an aside, being dismissive of the number of (US-type) libertarians there are. Of the people signing the petition, there are people who think that their team is for a pardon, and people who actually hold an opinion personally and are for a pardon. The former group might well have a different opinion next week if they believe their team does. The latter group are mostly those who were hard-core Obama supporters, whether or not they still are. The largest remaining block of people in the latter group are libertarians, but there are probably few of them. I would guess that right-leaning people who are outraged about the NSA activities would nevertheless feel uncomfortable calling for a pardon for Snowden.
