Why Super Tuesday II is important: Analysis by Anthony Zurcher
For Republicans, this latest slate of nomination contests is important not just because of the number of convention delegates up for grabs - 349 - but how they will be apportioned.
While the first Super Tuesday had a whopping 595 delegates at play, 15 March marks the first time states can hold "winner-take-all" primaries. The entire batch of delegates is awarded to the winner with even the narrowest plurality of the total state vote.
The Democrats don't play the winner-take-all game, but that doesn't mean that this isn't a pivotal day for their presidential race as well.
Although Mrs Clinton has a solid delegate lead, Mr Sanders is riding a wave of momentum following a shocking upset in the Michigan primary. Now all eyes are on whether he can outperform polling once again, particularly in states that are near Michigan, like Ohio and Illinois, and have similar levels of white, pro-union, working-class voters who have been receptive to Mr Sanders's economic populism and anti-trade-deal rhetoric.
