But then how will they make money? They only make a $174k base salary and a 15% cap on how much they can earn from other employment sources. I'm only saying this semi sarcastically. Often the senator's aides earn more than the senators themselves.

There's momentum on this, including from within Congress. I think it's likely in the future. I don't see it happening before at least two more Congressional elections.

Not to say they shouldn't be prohibited from trading in more markets or all markets, but prediction markets are so narrow in scope there could be a market on the way a particular senator votes on a particular bill. There will definitely be prediction markets made on the outcome of major proceedings the senator would be voting in, such as confirmations, on multiple platforms.

Exactly!

If we're gonna give this actual attention, we should be focusing on the fact that they should be banned from any form of insider trading or major conflict of interest!
