MSNBC host Chuck Todd suggested on Tuesday that President-elect Joe Biden will have "failed" if he is unable to deliver 100 million vaccine doses during his first 100 days in office. "Let's be realistic," Todd said on his Meet the Press Daily program. "Biden's first crucial task is to vaccinate America, to fulfill that promise to get 100 million vaccinations in his first 100 days." "The ultimate success or failure of his presidency may hinge simply on that one promise," the MSNBC host continued.
