It feels as if the Democratic primary has been going on forever. Ten debates. Twenty-eight campaigns launched, 23 folded. Hundreds of millions of dollars in advertising. And yet, despite all that, only 149 pledged delegates—of an eventual 3,979—have been awarded so far. Nothing has actually been decided.

With strong showings in the first three states, Vermont senator Bernie Sanders (58 delegates) is the person to beat. But former vice president Joe Biden (50 delegates) revived his moribund campaign with a landslide victory in South Carolina over the weekend. That result prompted former South Bend, Indiana, mayor Pete Buttigieg and Minnesota senator Amy Klobuchar to end their campaigns, which will likely push more moderate voters toward Biden. (But not necessarily! Voters are unpredictable.) Biden and Sanders now look like the clear front-runners, with Massachusetts senator Elizabeth Warren and former New York mayor Michael Bloomberg jockeying for third. But with so few votes locked in, everything remains highly speculative.
