He likely doesn't have one. The vast majority of his data is not based on fact. However, I do agree here. These things DO make it more likely fraud will occur. That is true. However, there is no proof of it actually happening on a scale that impacts anything. So it's still solving a problem that doesn't exist. Were I wrong they'd be able to prove it. They cannot.
Bank on Trump claiming fraud no matter what, he's already prepping to do it. Win or lose, proof or not. And it's an absolute travesty that you and yours allowed this to happen. There were other america first idiots you could have voted in. Instead you chose a criminal rapist who is unable to tell the truth and is a provable moron.
A lot of you will be asked some day by kids or grandkids if you actually voted for Trump. You will either lie or answer their questions with shame.
