First off, Trump is no Reagan. He's closer to LBJ.
Secondly, there will be no 1980 landslide because the electorate make up is different than it was in 1980.
However, too many assume that the rest of the country sees Trump the same way us conservatives do. Yes, I know. His negatives are on par with her's. However, and I understand this is just anecdotal evidence, but many people I hear and overhear have a sense that in this email thing, Hillary has gotten away with something others would not have and that she has benefit from the fact that there are laws for the elite and laws for the rest of us. And never underestimate the loathing and anger the average citizen has for Washington DC and it's occupants.
This is a disappointing election for conservatives. No question on that. And someday, conservatism will be called upon to truly "Make America Great Again." But, for now, the average citizen doesn't think like we do. They just know they are disgusted with what's going on. They don't compare Trump's soft statism with Hillary's Marxism. They just know that they don't like the direction of the country and might decide to take a risk with a Trump presidency. Hillary embodies everything they hate about Washington politics.
