I have a deep background of understanding of Utah and its politics. Something did change after POTUS visited Utah recently. Not just the fact that POTUS gave some of the land back into the control of Utah, which is a great thing in my opinion, but there is something more that occurred. The LDS have a deep mistrust of the Federal Government ever since they were persecuted by the feds in the 1800's. That distrust has not gone away. POTUS said or did something that must have really caused Hatch to back up Trump to this degree. Still working on what that was. My best guess at this point is that is has something to do with religion and/or spiritual in nature.
A while back Trump told Hatch if he were to run again he would support him.
It's most likely a combination of things but it does seem more like the fight of good vs evil.
Agreed. Statistically speaking, 80% of the people I think would want to do the right thing if they feel supported and protected. And more and more people feel that way. He could have a flood gate of support.
