Some call it an open convention, while others prefer the terms “contested,” “disputed,” or “brokered.” Whatever the words, Trump rivals Ted Cruz, Marco Rubio, and John Kasich are trying to accrue enough delegates ahead of the July convention to deny the front-running billionaire the necessary majority on the first ballot — forcing a second ballot, something the Republicans have not seen in more than half-a-century.
Convention delegates who are pledged to back a certain candidate on the first ballot are released from their commitments in subsequent rounds of voting — at exactly which point depends on the state — giving the non-Trump candidates a chance to pull the party in their direction.
