(KMSP) - Primaries are underway Tuesday in Ohio, Florida, Illinois, North Carolina and Missouri. Florida Sen. Marco Rubio and Ohio Gov. John Kasich are both hoping to pull off victories in their home states and put a squeeze on Donald Trump's delegate count. Here's an overview of what's at stake on Elimination Tuesday:
