His personal failures have never altered people's devotion to his ideology. His ideology informs each position and policy that the Left have.

Frankly, at the time, his association that jews were the ruling class of world elites that oppressed society would have had more support then than it does now. While he would not have claimed that it was inherent to jews, he would claim it is inherit in all bourgeoise as part of their material condition. This is why he referred to Christian Capitalists as "internally circumcized".

There is no way to get around the jew-hatred in Leftism. It's pre-built into it. The only issue is how emergent it is during various times and places. Right now, we are seeing a very hard upswing from the mid-twentieth century in jew-hatred among the Left. The UK's "Anti-Semitism Row" from a few years ago, and the soft-handed approach Islamists and Black National Socialists have received is quite telling.

It is not merely that jews are being identified as "the worst form of whites" among the racialists; but they are also being targeted for being "over-represented in finance, landlords, and c-suite positions".

No amount of funding from AIPAC is going to strengthen that bulwark as the Leftists return to their natural, jew-hating roots.
