If anyone wants to read a well-intentioned and astoundingly dumb essay on what a good, post-Trump Republican party would look like.
The GOP already wanted to take a different route post 2012 especially after the primary clown circus. They wrote entire studies on how to change the party and appeal to a broader audience.
Jeb Bush launched his campaign on a number of those ideas. And unlike Romney only did a fake tan and spoke two words in Spanish, Jeb Bush had a latino wife and spoke fluent Spanish.
With Bush as candidate (and perhaps Rubio as VP), the party thought that they would lock up the latino vote. It spooked team Clinton how well Bush's platform polled if they didn't tell people it was Bush's.
Especially among minorities.
Then the madman came down the escalator.
Anyway Gray Connely pretty much nailed it when he said: "Conservatism won't work unless people have something to 'conserve' and the younger generations own nothing"
Looting the people of their wealth through taxpayer backed bank bailouts, wars and denying young people the chance to buy their own homes, cars etc. ruined conservatism more than any populist movement could.
The cycle of job -> home -> familiy -> retirement that conservatism is build upon has been utterly shattered.
