Of course I am biased. I already stated so. No one knows the true numbers and that is why one cannot make a totally objective judgement on the matter. We DO need to track this very seriously IMO.
Your links are pretty weak. The first and last relate to the same incident in NV. The middle brings me to a login page. Not interested. Further, the last is CBS which is far more biased than I and has lost all credibility in this election.
Whoever it is that is involved in voter fraud needs to do time and lose their right to vote permanently. Unfortunately the ridiculous lengths to which we have gone to ensure that everyone, living, dead, disturbed, demented, etc gets to vote virtually ensures that voter fraud will be the determining factor in future elections. perhaps in this one. In fact, I think that is likely. A few thousand votes in one or two select states could easily throw the election. Just ask the liberal democratic union scum that threw the 1960 Presidential election. What about the swearing in of illegal aliens in Kali and busing them to the polls, they bused drunks to the polls in Milwaukee(2000) after giving them cigarretes, etc. I watched the crap that went on with the recount in FL in 2000 also. Now show me something similar that Republicans have done, not that weak ass shit you have linked above.
The bottom line is there needs to be legislation that forces those in the US to vote on the proper day at the place appointed. PERIOD. If they are too fucking stupid to figure it out they are too stupid to vote.
