What makes Super Tuesday so super – a state-by-state guide

Iowa is the first-in-the-nation caucus. New Hampshire holds the first primary. Nevada and South Carolina are dramatic, but Super Tuesday is the solidifier of presidential campaigns. This year, that’s particularly true, for both Democrats and Republicans.

Will the vaunted Hillary Clinton “firewall” hold on Super Tuesday, or will the furious Bern regain momentum?

How big a lead will Donald Trump walk away with, and will the results narrow the Republican field enough so that only one or two opponents are left to try to stop the New York billionaire.

Republicans will battle for 595 delegates in 11 states Tuesday, all divvied proportionally. And 461 of those will be awarded in Southern states, where Trump is mostly polling very well. The Democrats will contend for more than 800 pledged delegates in 11 states, versus the slightly more than 150 they have earned in four contests so far.
