On Super Tuesday, 12 US states all vote on the same day. This year it's March 1st, and up for grabs are some delegate-rich states including Texas, Virginia, Massachusetts, and Georgia. In total nearly a quarter of all Republican delegates are awarded that day, and about a fifth of the Democrats' delegates. Now, how these votes are divide depends on different rules in each party, different rules in each state, and how well each candidate does. But what Super Tuesday does deliver is a lot of votes all at once. Those who do well often go on to become the presidential nominee of their party. Those who do badly often drop out of the race when they don't have enough votes or money to continue.
