If you want a serious source you must delete the N.Y. Times, msnbc, nbc, abc, cbs, cnn and or just about all of the msm. So who is left?
What you demonstrate is a propensity for hear no evil, see no evil as in none are so blind as he who refuses to see.
The 3 million illegal voters is nothing but an unproven conspiracy theory with zero evidence to back it up and only mental midgets believe it. There would be plenty of indisputable evidence of voter fraud on that massive of a scale and it would be easily proven.
The Government Accountability Institute concluded in its report that thousands of votes in the 2016 election were illegal duplicate votes.
The Institute points out that the quality of the voter registration data in some states is very poor, with missing and obviously incorrect information.
We have serious, substantive problems in our voter registration system across the country and that voter fraud is, without a doubt, real.
New Report Exposes Thousands of Illegal Votes in 2016 Election
The Government Accountability says thousands. Not even "tens of thousands" or "hundreds of thousands".
That is a far cry from 3 million.
From your link: "The Institute compared the lists using an “extremely conservative matching approach that sought only to identify two votes cast in the same legal name.” It found that 8,471 votes in 2016 were “highly likely” duplicates.
Extrapolating this to all 50 states would likely produce, with “high-confidence,” around 45,000 duplicate votes."
45,000 duplicate votes amounts to 1.5% of the 3 million you claim.
