This was never meant to be a TV ad. It was a video message sent from Block to supporters. It came to me via email, and it was a private link to the video (it is public now, obviously) Block explained all of this himself talking to Megan Kelly.
The media took it and ran with it and turned it into a TV ad.
Either way, the reaction to it has been pretty neutral - some love it, some hate it, most don’t care. It is a non issue
