They use the same shady economic methodology to promote their policies.

If you follow the news, you’re familiar with “IMPLAN”, albeit indirectly. It’s the software package underlying the studies that pro sports teams, among others clamoring for public favors, use to claim that each new stadium will generate several gazillion dollars for the local economy—supposedly justifying a massive public outlay. Here’s a study using IMPLAN to justify a new Sacramento Kings stadium; here’s another that looks at the proposed Santa Clara stadium for the 49ers and another that attempts to justify a new stadium for the A’s. There are studies looking at the impact of the Mavericks’ American Airlines Center, the Packers’ Lambeau Field, and Oriole Park. And, of course, there are countless others: whenever someone wants to make preposterous claims about the benefits of his pet project, he’ll inevitably turn to IMPLAN or a similar package.
