From VDare: 93% Of Democrats Think It's Important That Fewer Whites Be Elected.
The article leads with a chart, which says that 75.1% of Democrats believe that "Whites are favored". The chart repeats later in the article. Problems:
The chart has no source.
The author falsely claimed that he always gives sources. Actually he had to be asked the source on Twitter because he hadn't given it. The source is these CNN exit polls.
To get the chart, the author did math on the CNN exit poll data. He did not show his work.
I checked what math he did by asking him on Twitter, since he didn't document it. His math was wrong. Where he got 75.1%, the correct answer was 75%. He added an extra significant figure to exaggerate how good his data was. He admitted I was right, but thought the matter deserved the comment "lol" rather than saying e.g. "My mistake, I will fix it."
The chart was brought to my attention by khaaan on Twitter, who questioned its sourcing.
