Is a Trump Loss Better for the Republican Party?

If Donald Trump wins, it would surely be better than a Hillary Clinton win. However, is it best in the long run for the GOP? If he does win, he will likely only be a one-term president since he will do many foolish things in office. So foolish, it could take the party down with him. On the other hand, if Clinton wins, she is so unlikable that she would likely only be a one-term president setting the stage for a conservative Republican comeback in 2020. By that time, alas, the Supreme Court would have been stacked by Clinton putting us into a 50 years dark ages. The choices are few. Pray.
