The main issue at hand is related to the fact that congresspeople are able to trade stocks on the basis of the insider information they have about upcoming legislation/changes to government policy.
I know. There always going to people smarter than me in more privileged positions than me. It would be weird if said people acted in a way that would incapacitate themselves. (Here, I am referring to the congresspeople)
There are laws in place that govern congresspeople's trades. These are ignored. They should be enforced. If congresspeople (or who?) are ignoring/not-enforcing the previous laws, what are they going to do with these new ones?
> a congresspersons power within the party is directly correlated to their ability to fundraise for the party
I agree, trading stocks is an easy, relatively passive way of doing this.
