AN UNCOMMITTED MOVEMENT WILL NOT BE CALLED FOR THE GENERAL ELECTION, REGARDLESS OF THE RESULT OF THE PRIMARY.
First off, it better not. If you think “Genocide Joe” is bad for palestine, try “Bloodbath drumpf”… I mean, maybe it is better to die violently and fast than slowly? But either way, whatever the pro-palestine movement is after, the democrats are their best choice, and by far. The alternative not only got stronger ties with the netanyahu government, but also a much lower overall IQ, zero consideration for legislation, international agreements, humanitarian matters, and democracy in general (which they have literally confused with the opposition party, for decades by now). You might not like biden, but from a humanitarian PoV, he is orders of magnitude better than anyone the GoP might select (and especially more so if it is drumpf).
Second off, I get that people are trying to “send a message”, but if it changes nothing aside from vanity numbers, it will have absolutely zero impact. The impact was “voting for Bernie”, and that is about 8 years too late now.
