There's also the much more substantive consideration that "public pressure", in the shape of a rally like this one, only works at all if there's a credible threat of meaningful action if the presented demands aren't fulfilled. There being no chance of that here, the upcoming rally is little more than a chance for the soi-disant protesters to get out in the fresh air and reassure themselves that they're Doing Something Meaningful.

It's not just a rally, we're also arranging a citizen lobby day for constituents to meet with their representatives and talk to them about why this is important: https://rally.stopwatching.us/lobbyday.html

Oh, well, that's totally different, of course!
