After reader more in depth, I think the criteria of level of "conservative" was pretty dubious and misleading.
From the article Criteria.....
Our Methodology
For our list of 15 most conservative companies in the USA, we’ve ranked companies based on the percentage of their 2022 election cycle donations that went to the Republican congressional candidates. We’ve sourced the data from Open Secrets, a non-profit organization that tracks corporate campaign-financing and lobbying.
Based on that criteria these companies could have made the list by sending big money to Turdle, Murcowski, Cheney, and Kinzinger.
Bogus, and sorry for not giving this article a proper vetting.
