But for Biden, this was about more than batteries. It was another example of what he views as a critical task of his presidency: Proving that democracy works amid the rise of brutally efficient autocracies. "My job is to show people that government has a role and that this loss of public trust in government can be rebuilt," Biden said, according to an aide in the room who was taking notes. "And this is a concrete way we do it."
Senior White House aides said the concept is constantly on Biden's mind -- a "central organizing principle," in the words of one senior official. It informs his approach to most major topics and the President regularly raises it in meetings, whether he is discussing foreign policy or electric bus batteries. And aides say Biden believes it is a key test by which historians will judge his presidency.
