It will be Newt. Trump needs somebody to defend him, since all he has now is Katrina Pierson and Scottie Nell Hughes, and they're both dingbats.
Newt has a way with words, but he'll have to own everything Trump says and does. And that's going to test his skill at justifying the unjustifiable.
My problem with him is he's thrown all his previous beliefs overboard. Running huge deficits, raising taxes on the poorest Americans, favoring certain businesses over others, cowering in the corner while Iran runs roughshod over the Middle East.
No, Newt's a sellout and I guess he's decided he'll go down in flames with Trump in November.
