It was a great night for Trump. Congrats!
It was a very good night for Cruz also as he outperformed all polls by wide margins. If it’s a priority for you that trump in not the nominee, stop sending your votes to Rubio and Kasich.
An interesting tidbit is that the State of Idaho has a rather large percentage of Mormons. I have not seen that mentioned anywhere.
Also, Crux was projected to likely win Idaho due to its proximity to Canada and he being born in Alberta. So, lots of Mormons and lot of Canadians to vote for Cruz.
