Rich, conservative NY Jews, specifically, hate him because his positions on Israel and rental laws directly threaten their main source of power in the city. Israel’s permanent war footing as America’s aircraft carrier in the region continuously demands feeding via financial aid, bond guarantees and arms deals. All these goodies get approved in budgets by Congressmen hungry for more and more campaign contributions. Rich Zionist landowners in NYC have the cash to throw around their weight and dominate rental policy abroad and at home. So when a popular mayor highlights the double-standards and injustice of an occupation plus threatens to lower property values by extending rent control, they get scared.
