we diligently participate in the process, we pay attention to the news on a very regular basis and pay attention to procedure to know what we have to do.
Which is precisely why no one minds you voting. Even if we don't vote the same way, I can assume you have bothered to at least have a basic idea of how things work, so I can rest somewhat assureed that you're not voting for a complete fraud.
But if you're going to lie around, wallowing in illiteracy, and wait for some DNC operative to offer to buy you a carton of Marlboros or an eight-ball of meth in exchange for your vote, then many of us would rather you just stay home, thank you very much.
This is a reasonable law.
