The 2020 presidential
election is still more than 14 months away, but with an early key deadline looming this week, the record field of
Democratic hopefuls is dwindling.
With a trio of 70-somethings breaking away from the pack -- former vice president
Joe Biden, independent Senator Bernie Sanders and fellow progressive
Elizabeth Warren -- four of the cash-strapped, younger or lesser-known candidates have so far thrown in the towel.
Only 10 of the remaining 21 candidates have met the qualifying criteria -- based on poll numbers and fundraising success -- and most of those are still struggling to catch up with the Big Three.
