Just thinking here...
He’s been in the race for so long now it seems only right for him to stick it out thru Iowa and New Hampshire.
Unless he’s doing it now so he can have some leverage in determining who’ll win both states.
My guess he will endorse Fred just like his Buddy in Iowa, Steve King.
I’ll bet Tanc was pissed when Gilchrist endorsed Huckabilly and would like to knock some wind out of those sails.
It would be a politically smart move for Tank at this point.
