Why would Cruz EVER drop out? His campaign and delegate stealing is all based on somehow sliding into the Republican Presidential nomination on the third or fourth ballot. Along with the help of his GOPe puppet masters.
Donald Trump better get enough delegates to win on the first ballot or the GOPe will skunk him with the help of Ted Cruz.
As long as the campaign money is there Cruz will not drop out. Even if it runs out he will not drop out.
It’s the motive for the campaign money and why it continues to flow.
Those who have motives to manipulate elections will continue funding the candidate they own. As long as there is still a tiny chance of having their collusion convention.
