This is not rocket science. The congress along with the willing dupes or perhaps accomplices in the state legislatures have created the perfect environment for voter fraud.
First was the Bill Clinton "Motor Voter" law. This allowed anyone to register to vote when they received their drivers license. Of course you do not have to produce proof of citizenship when you register.
I know of three immigrants, not U.S, citizens, who have registered in this fashion.
I wonder how many others have crossed our borders and did the same thing.
If properly organized a foreign country could take over small towns using this method until they have the majority in the county then the state. Think about it.
Second is the "Absentee voter's Ballot". There are a number of things wrong with this.
The foreigners could request absentee ballots so they would not have to go to the polls or show photo ID, making it easier not to be recognized as Non citizens.
Also nursing homes are full of mentally demented elderly persons who receive their ballots and have a willing staff member at the home fill it out for them. Of course the staff member will vote for raising a tax or implementing a new tax from which the nursing home receives a benefit.
Also, it is not difficult to keep track of deceased people over the past year by requesting copies of death certificates from the your county. These are public records. Then request the county send an absentee ballot, in the name of the deceased to an address where the conspirators can then fill out the ballot(s) come election time.
Thirdly is the lack of photo ID at the polls. This should be a no brainier, but the Democrats have been successful in keeping this from becoming law. (is it any wonder why?)
