The head of the company that was switching voter registrations from Democrat to Republican in last year's election was actually convicted, but not of that offense. He was convicted of voter fraud himself. Several states are investigating his company over the switching of the registrations, and from what I have read so far, it looks like those investigations are still ongoing.

Here's some background on that story...

If the person waging this campaign against ACORN was in the least bit concerned about the validity of our election processes, they would also be waging a campaign against those who help the Republicans cheat as well. But they are not in the least concerned with the validity of our elections processes. All they care about is making sure the Republicans win at any cost. Even if it means overlooking illegal practices committed by the Republicans themselves.
