According to The Washington Post, former DNC Chair Donna Brazile recalls in her forthcoming book, Hacks: The Inside Story of the Break-ins and Breakdowns That Put Donald Trump in the White House, that she thought about replacing Hillary Clinton on the Democratic ticket after the candidate fainted at the 9/11 memorial:
... Brazile details widespread dysfunction and dissension throughout the Democratic Party, including secret deliberations over using her powers as interim DNC chair to initiate the process of removing Clinton and running mate Sen. Tim Kaine (Va.) from the ticket after Clinton’s Sept. 11, 2016, collapse in New York City.
Brazile writes that she considered a dozen combinations to replace the nominees and settled on Biden and Sen. Cory Booker (N.J.), the duo she felt most certain would win over enough working-class voters to defeat Republican Donald Trump. But then, she writes, “I thought of Hillary, and all the women in the country who were so proud of and excited about her. I could not do this to them.”
One can’t help but wonder about the disruption that such an exchange would have caused, and whether a Biden/Booker ticket could have triumphed over President Trump.
