Not clear why this supposed Bernie Sanders supporter would be going to the right-leaning tabloid with this story, and no corroboration that any of the alleged fraud happened. The Post offers only that they corroborated the person’s identity, rap sheet, and work as a “consultant to various campaigns.”
The story, despite the lack of evidence this fraud actually took place in any election is already getting some traction on the right, including being RT’d by Donald Trump Jr.
