I seen that. But don't hold your breath about these corporate, wall street firms, banking etc to look at the rest of the agenda. But they'll still support the lobbyist to get those who they cut off donation to lobby them for their vote on the stuff they want.
Then there's other ways to get your donations to them, although not directly. Donating to the RNC or to the Republican senate campaign fund or to the Republican congressional campaign fun. Then you also could form a super pac. Donating to pacs is a great way of saying you not donating to their campaign, yet making sure they get the money and that they know where the money came from.
Regardless, all these donations regardless as to who, what is just another way of buying congressmen and senators. Legal buying.
