Where giant multi-national corporations the size of Intuit or H&R set up HQs has less to do with their politics, and more to do with their bottom lines and the talent they are trying to aquire.
Intuit needs developers, UX/UI designers, entire tech infrastructure as they are a SaaS and Software Business. H&R Block is a franchising company with some enterprisey software (that's a lot more complicated to use than any of the TurboTax editions) that the tax preppers use.
A lot less tech goes into H&R Block than Intuit, so H&R Block can be in a lowish-noish tax state like Missouri or Kansas and take the decent developers that they have to maintain and update their backend tax-prep software.
I understand that, my comment was more to my parent that was saying the problem was republicans and corruption. While I do think there is corruption involved; companies their politics and policies are made by people who work in the companies.
With Intuit being a company in an area that is overwhelmingly liberal, I would hazard that the majority of the people working there are as well(It is possible that the key positions are occupied by conservatives but over a period of years and consistently makes it less likely.).
