Not a problem for Trump. The Evangelicals there seem to be strange bunch, not even close to the Republican Party mainstream overall. They support strange people, like Huckabee, just because they pray a lot (or so it seems), they supported Carson because he said a few things, then they hung on to him for dear life as he self-destructed, I guess because he’s black. Cruz has targeted this bunch from the beginning, while Trump (obviously) has not.
The result of not winning Iowa, besides losing a relative handful of delegates, is that funding can dry up...the money stops flowing in. Something that Trump doesn’t have to worry about. To him it’s just a small state, nothing more.
I’m not worried about Trump.
I posted this to point out the schizophrenic internals that show Trump winning most major categories but losing the total.
