So they can vote themselves out to do the right thing, and they purposefully allowing themselves to invest in the stock market with insider information. My cynicism tells me they are throwing this bone to divert attention from the stock market loophole
I get what you're saying but they did also vote themselves a restriction on stock trading in 2012, so the same behavior as this? If prediction markets get really profitable you might expect the same loophole there too.
better is always good
when something you think is bad gets better but not better enough, say "more please"
i'm not sure it's productive to think this way. senators could be making more money on prediction markets. they took a nice step which will lead them to make no money on prediction markets (less money overall). it also sets a precedent which could easily be applied to the stock market.
what you're saying is probably on the mind of at least one Senator, but all things considered, this feels like a net-positive move which they didn't have to do.
