The momo is good for Sanders in IA, I think momo is a wash in the GOP.
The likely outcome based on what generally happens in IA is Cruz and HRC.
Both have superior ground games vs. their leading challengers.
It is ground game that has given us the Santorums and the Obamas in IA.
On the GOP side when push comes to shove the evangelical wins. Both the Quinnipac and Monument poll breakdowns of self-identification and past participation and planning on attending with somebody or alone all point to good ol fashioned IA peer pressure - Cruz.
The moderate/slightly liberal young first time caucus angry trump supporter is going to have to go into somebody's living room that smells a wee bit like moth balls, join hands in prayer, discuss the candidates, join hands in prayer again, and then vote.
While Bern is not so encumbered on the other side, and he has a decent ground game, I think HRC will carry the day.
That said, a relation who did some stuff for HRC (and heck, has a picture with her) sounds like she feels the bern. And she's evangelical. So what do I know.
