Cruz’s campaign sent emails to their precinct people before Steve King did anything on Twitter. It was based on a clip that aired on CNN. That video can be seen at https://m.facebook.com/story.php?story_fbid=1085531334800368&id=100000305365400&_rdr
(or I’m told it’s also at https://www.youtube.com/watch?v=XBfEfKZ6rBk if you don’t want to go on FB)
In that clip, which Jake Tapper said was based on information directly from Carson), they said (accurately, based on Carson’s campaign website events list) that Carson would not be going to NH or SC. They said that everybody knows that a person who doesn’t go to NH or SC is giving up.
The Cruz campaign sent out emails to their precinct people saying that the media was reporting that Carson was not going to campaign in NH and SC, and Carson’s supporters should know.
I know you’re a great researcher, so thanks very much, but I think the damage was done with Congressman King’s Tweet. It’s always best to check directly with Dr. Carson or his campaign.
