I mean, I’m pretty sure Sanders is well aware, but this is who he has always been his entire political career. He will try to make it an issue, try to make a stink about it, be ignored, and then later be remembered as being on the right side of the issue.
I have to say, I would have given up long ago, so it seems to me he’s a good egg for continuing to fight the good fight of trying to bring attention to these issues despite how often he has been ignored.
Do I think his way of doing things is working? I’m pretty sure it’s not, it could if there were more people like Sanders, but as he’s a minority of being on the right side of these issues, there’s only so much he can do to raise the issue and get others to care. While it’s commendable, you’re not wrong in seeing it as foolhardy and pointless because, well, it pretty much is. (At least not without a significant number of others at his back, which he does not have, politically.)
But it’s how Sanders has chosen to fight his fight, and it’s at the very least respectable, if unsuccessful.
