I know I'm new here, but it disturbs me greatly to see such claims thrown about without any substantiation. Voter fraud is a very serious charge and in spite of the Republicans always crying "voter fraud", it almost never happens in our country. http://www.nytimes.com/2007/04/12/washington/12fraud.html Voters are far more likely to be disenfranchised than to show up to vote under fraudulent terms. http://www.nytimes.com/2008/10/09/us/politics/09voting.html
There is a difference between registering someone to vote and them actually coming out to cast a vote, which is what a "voter" is-- someone who votes. Therefore, it is impossible to have voter fraud before a vote is cast. As I understand it, Acorn flags registrations it sees as potentially fraudulent and, by law, they have to turn them in. Even if Acorn weren't cooperating the way they have been, the fraudulent registrations to the number registered is extremely low.
Here is a link to an article which sums this, non-story, up quite nicely. It's partisan but has plenty of links for anyone interested in finding out the truth. http://www.guardian.co.uk/commentisfree/cifamerica/2008/oct/13/election-acorn-voter-fraud
BTW, I've been lurking for quite a while and have only jumped in occasionally. Politics are not for the faint of heart and my heart just is not strong enough for some of the political discussions around here. LOL So, I just read and glean what I can from those wiser than myself about all kinds of topics.
