Vance is staking out more of an "tariffs/industrial policy" approach as opposed to a Reagan/Friedman free markets ideology.
Perhaps he's currying favor with his boss... or trying to distinguish himself from Rubio, who's very pro-freedom oriented on everything.
Trump has never been a Republican idealogue... and has the same OCD tendencies as the Dems.
Vance wants to be his heir.
It's not clear how traditional Republican donors will react.
