evidence: Most recent vice presidents have been viewed as important presidential advisors. Walter Mondale, unlike his immediate predecessors, did not want specific responsibilities to be delegated to him. Mondale believed, as he wrote President-elect Jimmy Carter a memo following the 1976 election, that his most important role would be as a "general adviser" to the president.[38][69] Al Gore was an important adviser to President Bill Clinton on matters of foreign policy and the environment. Dick Cheney was widely regarded as one of President George W. Bush's closest confidants. Joe Biden asked President Barack Obama to let him always be the "last person in the room" when a big decision was made; later, as president himself, Biden adopted this model with his own vice president, Kamala Harris.[70][71]
