To make the March 15 debate stage, candidates needed to have been allocated at least 20% of the total number of pledged delegates allocated across all of the following contests: Alabama, American Samoa, Arkansas, California, Colorado, Democrats Abroad, Guam, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nevada, New Hampshire, North Carolina, North Dakota, Northern Mariana Islands, Oklahoma, South Carolina, Tennessee, Texas, Utah, Virginia, Vermont and Washington. The allocations need to have been made by by 9 a.m. ET on March 15. The total delegate allocation was determined by adding together all of the delegates allocated to candidates by CNN or the Associated Press, according to the Democratic National Committee. The number of delegates needed to qualify for the debate was determined by multiplying the total delegate allocation by 0.20 and rounding the result to the nearest whole number. The candidates’ delegate percentage was calculated by dividing the number of pledged delegates allocated to them by CNN or AP by the total delegate allocation and rounding the result to the nearest whole number. Who did not make the debate stage? Hawaii Rep. Tulsi Gabbard, the only other Democratic candidate still running for president, did not qualify for the debate stage. Gabbard has won a total of two delegates from the nominating contests. What happened at the last debate? The last debate took place before the South Carolina primary and the Super Tuesday contests. At the time, the candidates were attempting to knock Sanders off the course of claiming the party’s nomination. Many candidates have dropped out since then, and Biden has since taken the delegate lead in the race, after picking up wins in South Carolina and key Super Tuesday states.
