Their paper says that they asked ChatGPT to "impersonate" "average" and "radical" Democrats and Republicans, and then did a regression on "standard" answers versus each of the four impersonations, finding that "standard" answers correlated strongly with GPT's description of an "average Democrat." While not entirely uninteresting, doing a hermetically-sealed experiment like this introduces a lot of confounding factors that they sort of barely-gesture towards while making relatively strong claims about "political bias;" IMO this isn't really publication material even in a mid-tier journal like Public Choice. Reviewer #2 should have kicked it back over the transom.
