I am glad that Trump has the winner of Iowa in 2012 and 2008 Huckabee and Santorum. That has to help some.
Agree with you on IA. Otoh, Trump’s campaign manager, Corey Lewandowski, is a bit of a cipher. He’s only 40, and as far as I can tell has never managed a winning campaign. He seems to be doing very well, though. Amazing that Trump saw something there above and beyond Lewandowski’s on-paper track record of wins and losses.
