In reality it was intentionally left out because it contradicted Obama’s official policy.

CHARLOTTE, N.C. (AP) — One of President Barack Obama’s top allies said Thursday that Democrats made a mistake when they omitted from the party platform a reference to Jerusalem as Israel’s capital.

“It’s not that someone had a plan, ‘Let’s back off the long Democratic Party policy that Jerusalem should be the capital of Israel,” Sen. Chuck Schumer, D-NY, told The Associated Press a day after the omission and reinstatement of the language caused dissension among delegates at the Democratic National Convention. “It was just sort of left out.” Told of the omission, Obama directly ordered the language to be restored, Schumer said.

The vote on the convention floor Wednesday caught many delegates off-guard and inspired some to boo, exposing divisions in the party over U.S.-Israeli relations.

When Los Angeles Mayor Antonio Villaraigosa, the convention chairman, called for a voice vote, the ayes and nays were equally loud. He called for a second. The result was louder but still uncertain. Villaraigosa appeared to look for help from the sidelines and then called for yet another vote. He then declared the amendment passed.
