By the way, just in case you hadn't figured it out, I really have no idea whether or not any votes have ever been cast by noncitizens. In fact, in 221 years of our democracy, I'd be amazed if there were not such votes cast. My statement was intended to be as farcical as the statement that millions of votes will be cast by illegal aliens in the next election (pdq at 11:08 am). If you can't prove something you present as a fact, and that statement about a future situation cannot be factual unless you have a time machine, than you should make it clear that you are actually expressing an opinion.
