Well I went to the original source of the tweets involving Don (dan?) Fairly who worked for the Cruz Campaign. According to the tweets the campaign is off the rails.
A campaign can only do so much with the material it’s given. In the end, the candidate has to be electable. The problem with Ted Cruz is, the more you get to know him, the harder it is to like him.
So, Trump fired his own campaign manager Roger Stone a few months ago. Roger Stone claims he quit. A campaign is a business. What business doesn’t sometimes fire people who are doing a bad job? Or have employees quit because they disagree with their boss on something? Move along, nothing to see here.
