At first blush, this looks like a mistake. A campaign would understand and recognize that someone who had not endorsed Ted would see his name and correct it- so surely they wouldn’t intentionally pull this stunt.
HOWEVER, when someone who worked for the Clandestine Arm of the CIA ( and who has a former Director of CIA AND NSA working for his company) is the campaign chairman -who knows what is intentional and what is a mistake.
Back in the day when I worked on campaigns a few times, sometimes what happens is some directive or event occurs and staff gets over-zealous. That's why Cruz's campaign taking Carson votes wasn't an issue until it came out that the rumor was spread and embellished by campaign headquarters.
Cruz's campaign has gotten snarky and lawyerly. They seem to bring things right to the legal edge, and figure they're in the clear or can talk their way around things. What they didn't factor in is that after the primary runoff was stolen for Cochran, people want decent campaigns.
JMHO, but it's another case of Cruz being so smart that he outsmarts himself.
