Hey, there are these things called numbers you know? We use them to count and measure things.
The Republican party membership is 90% White. That's a fact. Not my opinion, a real fact.
That, 2 out of 3 White voters, votes Rebublican. Is also a fact.
That every racist I have known for the last 30 years, voted Republican. Also a fact, but the sample size is to small to draw any meaningful conclusions from.
You see how this works? You can measure things, and that gives you the information to know how White voters (as a group) voted.
There's a whole branch of math just for analyzing data like this. We call it statistics.
What part of "my analysis is numbers based" didn't you understand?
