A huge crack has surfaced in Obama's Jewish base in the person of Alan Solow, one of the president's closest Chicago friends and long-time supporters. Solow, who was named chairman of the Conference of President of Major Jewish Organizations last December, just released a highly critical statement on behalf of the 52-member group, in which he thoroughly disagrees with Obama's demand that Israel halt all construction of Jewish housing in East Jerusalem, including the Old City -- the holiest place in Judaism.
