Unbelievably depressing poll results from CNN:

Democratic presidential primary 2020

Former Vice President Joe Biden holds the most widespread support when potential Democratic primary voters are asked to rate the chances they would support six possible candidates for the party's 2020 nomination.
A broad 84% of Democrats and Democratic-leaning independents say they are likely to support a Biden bid for the Democratic nomination, two-thirds of whom say they are "very likely" to back his candidacy.
