Trump is conservative. He is just returning the Republican party back to is protectionist, nationalistic and patriotic roots.
Don’t know that I agree that Trump is truly “Conservative”.
The real issue is that “Conservatism” as it’s been preached for the last quarter century, at least on the economic side (free trade, globalization, service economy, outsourcing, Milton Friedman supply-side economics) has been soundly rejected by the voters. The GOP had close to thirty years, and could not close the sale.
You can debate the philosophical merits on whether that’s a good thing or not. But it’s a FACT! Mitt, Ryan and the gang had better get a clue.
