> Lobbies basically work in favour of the super rich.
One of the most widely respected lobbies in America is the Fraternal Order of Police. And I don't think anyone would consider them super-rich, or even "rich".
My point is that there are plenty of lobbies in America which are powerful and work on behalf of the non-rich. Fraternal Order of Police is the most obvious, but various unions are quite powerful as well depending on what State you're in.
NRA may be bankrupt, but their political strength is what caused so many to donate for their cause as well. I don't think NRA is traditionally seen as a rich-person thing either.
Think of the "heavy hitters" of American Politics: ACLU, NAACP, NRA, FOP. Decidedly working for non-rich causes. EFF is arguably for rich people (since it represents tech freedoms, and tech is generally rich).
