March 11, 2016 — March 1 earned the billing of “Super Tuesday” because 13 states held a primary or caucus that day, but the real deciding date at least for Republicans is next week’s Tuesday, March 15.
The true action in the coming days is on the Republican side despite Sen. Bernie Sanders’ upset Michigan victory earlier this week. Should Donald Trump win both the key Winner-Take-All states of Florida (99 delegates) and Ohio (66), he would isolate himself as the only candidate able to win a first ballot victory.
If Trump converts Florida and Ohio, and places first in the proportional states of North Carolina (72 delegates) and Illinois (69), as polling currently suggests, while taking a significant share of the Missouri congressional district Winner-Take-All format (52), he will likely fall into the range of committing approximately 712 delegate votes by next Wednesday morning. This means he would need 53.4 percent of the 983 available delegates from the 22 post-March 15 remaining voting entities in order to secure a first ballot victory.
