The schoolhouse rock version of how a bill becomes law is basically pure fiction at this point. Certainly at the federal level I'm not sure a single so-called legislator is competent to draft a bill. Occasionally they will have their staff draft some showboat bill that will likely never even pass committee, but almost all the bills that become law are drafted by some interest group or other, who then hire lobbyists to find a "legislator" willing to rubber stamp it.
It's surprising that it's not more of a well known fact that the USA isn't even remotely a real popularly representative democracy, given how completely obvious it is to all but the most casual observer. Princeton even published a study on the subject[1].

And that study is false; what it actually shows is that elites and average citizens agree on most things that pass, not that only elites approve of them.

Remember, when you come across some cynical information that shows the average person is a sheeple/NPC/etc, it’s not true! Average people are usually right.
In those cases where average people and elites do disagree, such as border security, the elites reliably get their way.
And yes I’ve seen the shoddy attempts to refute the Princeton study. They’re unconvincing.
