The problem described by the article seems like a case of violating dimensional analysis, rather than Simpson's paradox. It might be more obvious if we use clear units: 50 scores voted for A in West, and 80 dozens voted in East. The article talks about "weighting" the results, which is exactly figuring out the conversion from "democrats in West" to a common unit, "single person", to allow proper arithmetic operations on them.
