What makes Super Tuesday so special?
After all, presidential candidates will have heard from four states by the time March 3 rolls around.
For starters, Democratic presidential hopefuls need 1,991 delegates to secure the party’s nomination. Nearly 70% of them are up for grabs on Super Tuesday.
With 14 states, one territory and Democrats Abroad voting on March 3 and 1,357 delegates at stake, it’s the closest thing Democrats have to a national primary. It paints the clearest picture of which candidate is appealing to a diverse audience, not just a particular wing of the party.
In half of the early-voting states, Iowa and New Hampshire, voters tend to be less diverse and more rural.
With a mix of white and non-white voters, Nevada offers the first true glimpse into the minds of minority voters.
And South Carolina’s Democratic Party is bolstered by its large number of black voters, who aren’t traditionally as liberal as other voting groups.

But on Super Tuesday, many southern states, who share the same ethnic makeup of South Carolina, are in play. Texas and its large number of black and Latino voters is the grandest southern prize with 228 delegates.
More liberal states like California and Colorado will also hit the polls.
The four early-voting states are extremely protective of their status as early voters. The Democratic Party reinforces their claims by preventing other states from scheduling their primaries or caucuses in February.
Ideally, the earlier a state votes, the more influence it wields in the nomination process. And candidates are more likely to visit those states and spend more on ads there.
By the time Californians headed to the polls in June 2016, the nomination process was nearly over. Despite offering the largest number of delegates, Golden State voters could only affirm what the rest of the country had already decided, not set the tone themselves.
This year, California has opted to move its primary voting to Super Tuesday and 415 delegates are in play.
Super Tuesday serves as a make-or-break moment for a lot of candidates. If they fail to gain a significant number of delegates, their path to the nomination becomes more difficult.
Donors will likely start supporting stronger candidates. And struggling candidates may feel pressured to drop out, endorse a front-runner and start the process of unifying the party.
Three candidates are vying for delegates in their home states this go-round: Sen. Elizabeth Warren (D-Mass.), Sen. Amy Klobuchar (D-Minn.) and Sen. Bernie Sanders (D-Vt.).
