Don't think voter fraud can happen?

Recently, I discussed the arguments for and against stricter voter-ID laws across the United States, specifically focusing on those that require photo-ID of some variety, pointing out using others' works that there was strong argument for and against such laws.

Now, it seems that the potential threat of voter fraud has been demonstrated with both more undercover "operatives" and at least one actual case of it.

Conservative "operative" (not sure what the best word is for him), James O'Keefe showed off video evidence illustrating the major flaws in the states where voting requires no real identification: he was able to impersonate actual individuals on voter registries and on 20 separate places, was not preventing from actually voting. In fact the only thing that seems to have prevented O'Keefe from committing actual voter fraud was his own actions in ending the "undercover operation". 

This however, was not the first time we have heard about the issue of voter fraud in the last 48 hours or so.

Voter-ID Laws: Disenfranchisement or Necessary Evil?

In something of a change from the usual political rant, we are instead looking at a major issue in American politics: Voter-ID laws

And instead of just talking about one side of the argument, I want to discuss and mention BOTH sides of this much-argued topic: Are such laws disenfranchising the poor and many minority voters or is it a necessary evil to combat voter fraud?
