I think, one decisive factor for MAGA's success in the recent elections is left antisemitism, as it created a rift among progressive voters.
In my opinion chanting "from the river to the sea" is antisemitic, because wether you categorize the Israeli warfare against Gazans as a genozide or not, one genozide doesn't justify another!
Secondly I don't understand, how you can not recognize the resulting rift among progressive voters as part of hybrid warfare.
