Then produce names, dates, times, and places. Produce specific allegations against specific people. Or, if you can't do that, then shut up about it. I'm sorry to be so blunt, but you can't just cry voter fraud unless you have specific charges and the proof to back them up. You need to be able to say who did it, when, and how. Provide actual names of deceased people who voted, and then provide proof that said person was dead on election day.
I'm not saying for you to go out and do the research, but since you believe the charges I assume that you can point me to a site where someone has?
Ah come on, after all that Democratic crybabying after the 2000 election, I think we have some leeway.
