Very rarely. Most of the consumer protection laws were passed before Reagan in 1980. We did get the CFPB after the 2008 financial meltdown but it's been under attack ever since.
So it should be as easy as buying tracking data and searching for Congressmen. We can put up license plate readers around Washington too, since that's legal.
Doesn’t really seem like the environment where the common persons going to get more rights or protections since the POTUS and SCOTUS are currently ripping those up while Congress sits in the cuck chair.
"Citizens" United (which allows unlimited corporate political donations by classifying them as "speech", for those out of the loop) has fundamentally changed the core incentive structures of the modern political landscape. To compare a pre-CU world to a post-CU world when it comes to matters at the intersection of corporate interests and government regulatory / legislative power is comparing apples to oranges.
We need to overturn CU if we want to be able to go back to a world where government serves people rather than multinational conglomerates.
Citizens United has to be the most inaccurately cited case. It did not 'allow unlimited corporate political donations by classifying them as "speech"'.
It ruled that the federal government was wrong to restrict the speech rights of some groups while allowing other very similar groups to still retain their rights. One of the major examples of this was the media industry. A for-profit newspaper company could spend whatever amount of money it wanted to on political speech. An identical company in a different field could not. This, the court ruled, was unconstitutional.
It also did not grant corporations personhood, the other thing people like to state that it did.
Frankly, I think it's much less of an issue than it's made out to be. If money meant so much, Donald Trump wouldn't have beat Jeb Bush on the way to beating Hilary Clinton.
To me, money in politics is the red herring to keep you from looking at the real election reform that needs to happen, some combination of open primaries (to remove the effect of primaries going to more extreme candidates rather than centrists) and an alternative to first past the post elections to allow people to vote for who they like without worrying about throwing away their votes (there are many different systems to do this, they're all major improvements).
The money in politics is used by the parties to back their preferred candidates and the voters go along with it in the general elections because they don't want to waste their votes. The money helps them do the bad thing but it isn't the bad thing.
