Honestly, as someone who once worked as, functionally, a lobbyist for a few days at a time, off and on, in addition to my regularly assigned job duties - I can say with absolute confidence that Corporations have almost no pull with politicians (excepting a select few, in select areas - like Disney + Copyright), because they spend too much time (and not enough money) working at cross purposes to one another.
The company I worked for manufactured a product.
There were legislative changes they could have sought which would have put Mfg's of add-on products on a more level playing field with them - but they didn't, because they had a hand in some of those companies. There were legislative changes that would have placed them at less mercy to the businesses that sold their products, and repaired their products. They didn't, because THOSE business did have a very effective lobbying arm, and did donate heavily in the community, and state laws left them with no legal choice but to work thru those busnesses.
Also, the company I worked for (and those in competition with it) had some ugly history to overcome - that the history was older than most voters didn't matter - we were the ones at the table who least smelled like roses, and the others at the table spent plenty of effort making sure the consumers/voters kept that image in mind.
I've seen how the sausage is made. I've participated in it. Frankly, it makes the first time you butcher your own birds look like an elegant and restrained art.
