Keller @ Large: As Biden Exudes Confidence, These Are Tough Times To Be President

BOSTON (CBS) – In front of the cameras, President Biden exudes calm and confidence. But behind the smile, he's got to be worried about what lies ahead. Biden never misses an opportunity to brag about the rapid pace of vaccinations. But while that has earned him high marks for pandemic management in recent polls, we need roughly 80% of Americans vaccinated to reach herd immunity. And the latest CBS News/YouGov poll shows 40% of us are hesitant, and the 22% saying "no" hasn't budged in months.
