In some circles, Joe Biden is being analogized to Reagan; both are seen as elderly, genial, disengaged guys who survive repeated gaffes because of their sheen of fundamental decency. For Biden, the analogy is a mixed bag, at best. Is it accurate?
Only up to a point. Reagan’s certitudes were based in nostalgia and hard right ideology; they didn’t call it the “Reagan Revolution” for nothing. He was viewed as a dangerous extremist even by many members of his party in 1980. Biden is a centrist determined, at least based on his public statements, to bring about moderate change with the assistance of members of both parties and to purge our system of the fleeting evils of Trumpism. He is essentially a conservative, not a “revolutionary.”
In other words, he is more like Eisenhower than Reagan, which is no bad thing, from my perspective. If you want a left-wing Reagan, vote for Bernie Sanders.
