You can absolutely vote out the politicians responsible for for giving authority to these regulators. In fact, it's your duty to vote out crooked politicians. Even when both candidates for an office are crooked, they won't be equally crooked. Figure out which will do the least damage and support that candidate despite their flaws.
And don't give up hope. Crooked interests are absolutely counting on voters' cynicism to allow them to operate.
It's not so simple as good and crooked. How can you even traceback which politician gave which authority to what regulator, and how can you possibly know that the opposing candidate would do a better job? Fringe issues like this are completely out of scope for voters and will not even show up on the politician's platform. If you care deeply about a fringe issue, you need to either hire a lobbyist or become a politician.
I am going to go out on a limb and guess that it is fairly obvious which political party in the United States takes regulatory issues seriously.
I think you might be greatly surprised by how much influence you personally can have on politics on a very practical level by interacting with politicians of said party in your district on a personal level.

It doesn't matter who gave authority to the regulator, what matters is whether or not they are currently responsible for that regulator, and are doing a good job of it.
There's a congressional committee on pretty much every department under the sun. Follow the chain of command.

"Billy really sucks at doing his job, but we can't fire him because we don't know if we hire someone worse" isn't a good reason to keep Billy employed. Keep sacking the ones that are doing a terrible job, until you find one that does a good one.
"Steve is our best salesman but he keeps burning popcorn in the microwave. Joe Janitor just put in his resume: I don't know if he's better with the popcorn but let's fire Steve anyway."
I'm belgian, living in Belgium and I know which american political party take regulation more seriously, which is more obviously corrupt and which is more socially irresponsible...
Just google "climate change republican party" and you will have a good summary about who should get your vote for the sake of your grand children.
