"Forty-eight percent of Republicans said they believe between 3 million and 5 million people voted illegally in 2016, while 17 percent said they do not, according to a new HuffPost/YouGov poll. Another 35 percent of the GOP said they were unsure."
A scary amount almost 50% of Republicans believe that our election was impacted by voter fraud. I think this statistic applies to whatever Trump says, that about 50% of his base believe it regardless of what he says.
