How do you eat an entire elephant? One bite at a time.

How do you corrupt an entire government? One congressperson at a time.

Pick the right one and it might.

Or spend $23,134,000 on all of the House and Senate.

You probably only need 15% of congress. Some of the unbought ones will follow, some would vote for your side anyway, and there are often unrelated things in the bill that will bring a bunch of those who otherwise don't care about this issue with.

In theory, to change discourse, you just need one expert and a few magazine articles and the rest is history.
