I'm as ardent of a #Nevertrump conservative as the next guy. You might think that swapping Trump and his baggage and his lying and his crassness and his strange ideas for a real Republican in Mike Pence would be as good as having Ronald Reagan back for 8 more years. It wouldn't. Here's why:
Trump was elected by traditionally Democratic blue collar states with an American jobs first populist message. Republicans will have to honor that and change their ideologies somewhat or they are going to be very sad in 2018.
If Trump is impeached, there will be a huge Democratic told ya so backlash.
I think that Trump is the best person to handle North Korea, because I think Kim Jong Un is actually afraid of him. I imagine Un takes his morning breakfast always thinking that he could be eating CIA poison, and he takes his morning stroll on cloudy days only because he's afraid of reaper drones. I'm not saying Un should be assassinated, as that might provoke war with China and Russia. I am saying that North Korea has to be stopped before setting Seattle on fire is an option. I also think that the Obama era politics of economic sanctions, harsh reprimands and the occasional CIA malware hack have only left Un more time to make bigger and more effective bombs. If those things don't work, then what does?
I also think that free market approaches to the economy and old school Reaganomics are going to lead to people having nowhere to work. There aren't that many jobs left that aren't automated. The party that does something about this is the party that is going to be in charge.
Also, for the day to day operations of America, Pence already runs the Presidency anyway, doesn't he?
