The Clinton family has made sporadic and often subdued appearances in the 18 months (538 days) since Hillary Clinton lost her presidential election. But we're about to see a lot more of them this spring.
Why it matters: This family has been on the national stage for 26 years — all or most of the lifetime of anyone under 50. Chelsea Clinton, now 38, was 11 when her father, Arkansas Gov. Bill Clinton, announced his entry into the race for the Democratic presidential nomination in October 1991. He was 45 then; is 71 now.
