Trump made a similar allegation about voter fraud by immigrants in the 2016 election because despite winning the electoral college vote, and of course, the presidency, he couldn't bring himself to accept that he lost the popular vote. What did he do? He, no one else, he, set up a task force to look into the issue and his task force found so little evidence that it was disbamded within a few months without even making a report.
Your claim about a 'random' study in 2017 is also nonsense, that particular one has been ongoing for 20 years and others have been undertaken during the same period.
You keep talking about evidence, evidence that neither you nor Trump can actually produce.....because it doesnt exist. All you, and Trump can do is make and repeat claims of fraud, claims of theft, claims for which there is not an ounce of eviidence. Frankly, if the Dems were so fecking clever as to fiddle the Presidential Election in so many Republican States, and do so while concealing the evidence from the GOP, the Courts, the House, the Senate, and the people, then I would argue that it is a great thing that the new President of these here United fecking States is one clever motherfecker.
