Showing the first two plots as a sorted scatter plot is kind of an odd way to convey the data. You'd have been better served showing a histogram of sorts and what the fitted t-distribution would be between your two data sets. The overlap between those two curves is what gives you the best visual representation of a statistical difference.

It's also not really clear how you are classifying the data. Is every data point a state? Are you classifying a state as "Democrat" or "Republican" based on majority vote for president in some election? This info is necessary to properly interpret your results. If that's what you're doing, that's also kind of an odd analysis, since the state as a whole clearly doesn't represent just one party, not to mention that the population differences in conjunction with their classification really ought to be weighted accordingly. You're destroying the whole concept of "per capita" if this is what you are doing.

The "t-test" number on the top left is confusing. Is that the t-statistic or the p-value? And why doesn't the top right graph have a number, especially when it looks more likely to have a statistical difference?

Your bottom chart has a typo. "Evangelival."

I see you post stuff like this regularly. IMO you ought to clean up your presentation quite a bit and give it more thought. It's kind of a mess.

The Library of Alexandria had maybe 100,000 books worth of scrolls containing ??? written at a time when the smart people thought disease was caused by bad air

There probably was some dope shit, but there's an order of magnitude more educational content on YouTube than burned in the LoA
