I dont disagree with the premise that the votes were wonky.....but..

the census bureau has nothing to do with voting or knowing who votes. Now if they said there were 154 million people legally eligible to vote and 158 million people votes that would be different.

But since voter turnout was only 62-66% they have not idea by looking at number of votes on nationwide basis. Have to do an audit to see how many people voted multiple times or how many dead/illegal votes there were. And they ain't releasing that info
