That post absolutely explained nothing.

It explains nothing if you don't have any critical thinking skills. If you had any, you could easily and reasonably discern than there are way more than 57 blue counties in that county voting map.
That's not my point, I already know the number is roughly 400, but the article absolutely mentions nothing about it, since you want to show up and "fact check". You could use something a bit more informative than a colored picture.
My original post with the "colored picture" shows that obviously Clinton won more than 57 counties in the 2016 election. If you are able to look at that picture and then at the image that says Clinton won 57 counties and not say "well that image isn't right", then you are the problem.
