Try this
Google "democrat voter fraud", then do the same for "republican voter fraud".
You will see that there are more than twice the allegations against the dems. BTW, be sure to read the allegations.
All the allegations prove only that the strategy of "pre-emptive strike" with or without any evidence of wrong doing is being followed by democrat zealots.
The voting forms with the unchecked box should not be excluded if that's all that is wrong but in the face of wild accusations and "pre-emtive strikes" who knows what the truth is.
