The Manhattan Institute poll adds to the increasing body of evidence that support for the Democratic Party and its candidates among American Jews has declined in recent years. The decline tracks with Democratic policies and attitudes toward Israel — particularly since Oct.7. These American Jews must wake up to the reality that the historic and principled loyalty toward Israel from the U.S. is no longer assured. Those in the Democratic Party itself, from its highest leaders to its future base, have revealed that their commitment to Israel is tenuous and they are not consistently in line with the American Jewish community. The clear lack of loyalty toward Israel and the disturbingly minimal support American Jews have received in the face of so much violence and antisemitism should be sufficient evidence to end the long-standing Jewish relationship with the Democratic Party.
