evidence: Harris is the second woman to become a major-party presidential nominee, the second Black nominee and the first Asian. In a 37-minute speech — roughly one-third the length of former President Donald Trump’s at the Republican National Convention in July — Harris retold the story of her upbringing in a "beautiful working-class neighborhood" in San Francisco’s East Bay. She described being a child of divorce who was raised with the help of people, "none of them family by blood, and all of them family by love." [...] Harris’ figure about how much it will cost families is higher than most estimates. A more recent estimate, from the liberal group the Center for American Progress Action, came up with a $3,900 figure but that was based on the high end of a 10% to 20% tariff range that Trump on one occasion speculated about.
