Reagan was in the same Boat and won by a landslide

You inability to make valid comparisons is....puzzling.

Reagan had been Gov and had run unsuccessfully for the GOP nomination. So there is no comparison in experience levels.

Additionally, without a hostage situation, and without the millstones of 7.5% unemployment and 13% interest rates for Hillary, you've no basis for predicting a landslide for Trump, of all people.
