After watching, I'm not sure if it's the amendment or the iffy vote count that gets the booing.
Even the Los Angeles Times is skeptical of the way the vote was handled:
It took three attempts to pass the language regarding Jerusalem and a subjective decision by the convention chairman, Los Angeles Mayor Antonio Villaraigosa, to decide the change had the required support of two-thirds of the delegates. To many listeners, the voice vote seemed at least evenly divided.Aren't Democrats the party that insists voting fraud isn't a problem?
Update: It gets better. Huffington Post says President Obama was behind the scenes pushing for the reinsertions. Does that account for the tone-deaf tally? Same HuffPo report goes on to say:
Even though the no's were again as loud if not louder than the aye's on the third vote, Villagairosa said he had determined that two thirds of those present had voted in favor. Boos filled the arena in response.Here's video of the vote as uploaded to a Republican YouTube account:
