Then I think the progressives need to have a little look at what happens next, if you think Biden is too pro-Israel then I'm pretty sure Trump's views would terrify them. We're having the same problem here in the UK, progressives are calling for the abandonment of Keir Starmer because he's a transphobic hateful, israel-loving, war-mongering non-progressive bastard.

The options are limited.

If you don't get Biden, you'll have Trump. Then you've got real problems. People don't have to like Biden - and democracy doesn't mean everyone getting what they want - it means people having discussions about things and reaching compromise positions. If progressives throw Biden away because of some misguided belief they're doing the world a service, they'll certainly have more to think about than Gaza in a few months time. :o/

Biden isn't the best President the US has had, but he's better than the alternatives.
