In any case, the Trump movement's whole response to this kind of thing was a combination of denial and "lol everyone does it", and it seems like that was enough for many in that camp.
>> For sure there are many factors that influence someone's vote. I think you're right - its more likely to cause leadership rotation within the parties where the rest of the factors are more similar (i.e. stance on gun rights, etc.). The challenge today is that incumbent politicians within their own party tend to have great name recognition among voters - but are more likely to be in the pockets of corporations.

Politicians already long on certain stocks can also profit from legislation that they are passing. Being privy to insider info which leads to continuing to stay long a stock is an advantage that wouldn't be detected by just sharing recent trades.
In addition to trying to eradicate insider trading - just shedding light on existing holdings by US office holders will have a huge cleansing effect that will go a long way to showing potential biases/conflicts of interest.
