The first 100 days of a two-term presidency mark about 3% of the eight-year span, but since President Franklin Delano Roosevelt, this brief early window of opportunity has been used to judge a new commander in chief’s agenda. President Biden's first 100 days are sure to look different than those of Democrats past, and not just due to the unprecedented challenge of a pandemic. Economic challenge was met by greater spending under Barack Obama than by his Democratic predecessor, Bill Clinton, and even more federal largesse will be doled out by Biden if Congress gives him his way. Other priorities have differed too.
