The thing about successful presidencies is there is an element of luck involved.
President-elect Joe Biden doesn’t deserve any credit for Pfizer’s Monday announcement that its COVID-19 vaccine appears to be effective — but he stands to reap the political benefits. If the vaccine is as effective as promised, and if it can be widely distributed to Americans during the coming months, the sense of emergency afflicting the country might subside over the next year. That, in turn, should help boost the economy back to something like normalcy.
Biden won’t exactly be responsible for those developments, since the work of creating the vaccine and other therapies started well before his election, but that may not entirely matter.
