From the opening gavel through most of the evening, the old Will Rogers trope “I am not a member of any organized political party. I am a Democrat” appeared to hold true for the first day of the Democratic National Convention.

Bernie Sanders supporters rained boos upon any speaker who uttered the name Hillary Clinton. They also jeered keynote speaker Elizabeth Warren as a traitor to the progressive cause. Not until first lady Michelle Obama delivered a speech that drew near unanimous acclaim did it appear that there would be any semblance of unity.

Sanders closed Monday evening’s session with a strong endorsement of Clinton, taking most of the air out of the Bernie of Bust movement.

Tuesday’s roll call of states to vote on her historic nomination may be the last chance for Sanders supporters to protest Clinton’s rise to head the Democratic Party. After she wins the nomination, it’s all about Hillary.

Her husband ,former President Bill Clinton takes the stage Tuesday night as well as House Minority leader Nancy Pelosi, both focused on giving the first woman major party presidential nominee a post-convention boost.
