It was 3AM because they blew the text messaging thing. They had planned on doing it at 10AM Saturday morning. But the media scooped them so they had to send it out.
Watching the folks at DU and KOS wait and wait and wring their hands all evening waiting for that text msg was priceless. Even after the media reported it, the secret service was at Bidens, they still thought it was all a ruse to deflect from who the real candidate was. Yea, right. The secret service is going along with a gag on the media.
As Forest Gump says “stupid is as stupid does”.
Obviously they put the guy responsible for the balloon drops in charge of the text message project.
