It's a data-driven article, so it had to make a very good use of data visualization. In my opinion it succeeds with plenty of maps and sheets, plus good analysis.
Maybe they could give the readers a chance to check data from their own precints or electoral districts. However I imagine the workload in creating that content would make it almost impossible. Could they use a bit of programming to solve the issue? I'm not so sure.
