Conventional wisdom: What to watch for Tuesday

ROLL CALL: Delegates will make some history in nominating the nation’s first major party female presidential candidate. But Bernie Sanders delegates are hoping to have their votes fully tallied. At last week’s Republican National Convention, Illinois Republican Party Chairman Tim Schneider called Gov. Bruce Rauner the “finest” governor in the nation when it was time for Illinois Republicans to cast their ballots. Wonder what Illinois Dems will call him.

MOTHERS “Mothers of the Movement” will try to put human faces on the nation’s gun epidemic. In what will be an emotional address, the mothers of Eric Garner, Michael Brown and Sandra Bland will talk about how the deaths of their children affected their lives and the lives of others. Trayvon Martin’s mother is also set to speak.

HEARING FROM THE FIRST FIRST HUSBAND?Former President Bill Clinton, who has toured the country in support of his wife, will be the must-see speech on Tuesday. Clinton last spoke at the 2012 convention, when he became the first former president to deliver a nominating speech. Expect a morale boosting speech with messages of unity.
