NORTH CONWAY, N.H. — The morning after the Democrats’ last debate in December, the Democratic National Committee announced the thresholds to qualify for the next one, scheduled for Jan. 14 in Des Moines: 5 percent support in four qualifying polls, or 7 percent in two early-state polls. With those steeper requirements in place, just five candidates have qualified so far: Joe Biden, Bernie Sanders, Elizabeth Warren, Pete Buttigieg and Amy Klobuchar.

Those who haven’t made the cut are getting angry about relying on the results of public polling — when no polls that count have been released since the last debate, on Dec. 19.

If any of the lower-tier candidates got a boost from that last debate, there have been no qualifying polls to reflect it. With just one week to go before the Jan. 10 qualification deadline, there’s been no way for Andrew Yang or Tom Steyer — who are on the fringe of making the debate stage — or anyone else (like Cory Booker, who needs a lot of help) to secure a spot.
