I’d summarize the graph as: probability of voting Republican increases with income up to $70,000 or so, where it reaches a plateau.
There are some hints of a pattern above that, but within the income range where they have data there are only slight changes which are inconsistent from election to election. What’s clear from their graphs is that someone with a $250,000 income has about the same chance of voting Republican as someone with a $75,000 income, and both are much more likely to vote Republican than someone with an income under $30,000.
Rich northeastern states tend to be relatively Democratic, and there is only a weak relationship between income and party within those states. The upper-middle-class liberals in that region are the main target of Stuff White People Like. But in the country as a whole there is a clear relationship between income and voting Republican, at least over most of the income distribution (although they don’t have the data to say what happens within the richest 1%).
