WASHINGTON — Americans from 15 states and one territory vote simultaneously on "Super Tuesday," a campaign calendar milestone expected to leave Donald Trump a hair's breadth from securing the Republican Party's presidential nomination.
Typically, the event — the biggest single day of voting in the country's drawn out, state-by-state primary season — has been a make-or-break moment for candidates as the race narrows.
On the Republican side, more than a third of the delegates who will be assigned to the party's national nominating convention in July are up for grabs on March 5.
