NEW YORK—Joe Biden and the Democrats are highlighting the party’s inclusive “big tent” Monday night as their 2020 National Convention gets underway with a lineup that features as many former Republican governors as “democratic socialists”—along with the star power of Michelle Obama.
The former first lady will stress Biden’s competency and character in a keynote address expected to draw sharp contrasts between the Republican incumbent seeking reelection and the man who was her husband’s two-term vice president, an adviser said.
