The sad thing is that voter fraud is almost entirely unprosecuted. Until we do that we will have more of it, every election. Those that do prosecute will be demonized and vilified as not letting "every vote count", suppressing minority votes, intimidating voters ... you name it. Gonna take some big brass ones to get that job done.
An interesting angle is that some of the worst, shameless, vote-stealing crooks have gotten so emboldened that they are now asking outside (non-U.S.) people to monitor the fairness of our elections. Wouldn't it be great if these people report the blatant cheating the dems are ready to do. Of course, those same crooks have probably paid off the observers already in a close imitation of Saddam's oil-for-food criminality.
