President Biden is “absolutely” staying in the presidential race, campaign chair Jen O’Malley Dillon said on MSNBC’s “Morning Joe” on Friday, calling him the “best person to take on Donald Trump.” Her assessment comes amid growing calls from Democrats for Biden to step aside. The Republican National Convention in Milwaukee wrapped up Thursday night with a lengthy acceptance speech from Trump in which he spoke about Saturday’s assassination attempt and basked in his party’s nomination. Trump and his new running mate, Sen. J.D. Vance (R-Ohio), plan to appear together at a rally in Michigan on Saturday. Biden is isolating in Delaware after testing positive for the coronavirus this week.
