I am saying that if you were trying to manipulate an election process that uses some type of electronic voting that you would do it like this:
The voting machine would not show you that it changed your vote. It would change it, behind the scenes.
Cruz not only has to win Texas, but win with 50%+ to get all of the delegates - A narrow win or loss means Trump still gets a nice chunk of that Delegate pie. And Cruz abandoned the other states to keep his hopes in Texas alive. Trump has a healthy lead in all of them.
Trump - massive delegate count
Cruz - needs huge Texas win to get back into race
Rubio - Cannot see him winning anything and 2nd place is still a loss
Kasich & Carson - Running to be relevant as a VP or Cabinet pick
