Meanwhile, on the Republican side, Texas Senator Ted Cruz has named former presidential rival Carly Fiorina as his vice-presidential running mate.

Sen. Ted Cruz: “After a great deal of time and thought, after a great deal of consideration and prayer, I have come to the conclusion that if I am nominated to be president of the United States, that I will run on a ticket with my vice-presidential nominee Carly Fiorina.”

It’s the first time in four decades that a presidential hopeful has named a running mate before winning the party nomination. The last candidate to do so was Ronald Reagan during his 1976 campaign.
