According to our child president Donald Trump, the existence of out-dated or inaccurate voter registration is proof that fraud exists, but his definition of fraud would include most of his staff and his own family.
White House adviser Steve Bannon, Treasury secretary nominee Steve Mnuchin, and Donald Trump’s daughter Tiffany were registered to vote in multiple states during the presidential election.
So are Jared Kushner, Trump’s son-in-law and close White House adviser, and White House Press Secretary Sean Spicer, both part of Trump’s tight-knit circle of insiders during the tumultuous campaign and new administration.
Anyone who has ever moved from one location to another is probably registered to vote in both locations. It's not fraud unless you try to vote in more than one location.
Actual instances of voter fraud are more rare than being struck by lightning while being eaten by a shark.
