There's no substantial difference between 'Trumpism' and 'Reaganism'. There could have been - Trump was uniquely positioned, among all Republican Presidential nominees, to endorse a Keynesian cornerstone like universal health care above the heads of his Party establishment - but this would have required the Trump movement to be a legitimately populist one, rather than a last madcap effort to staunch the self-destruction of the Reagan coalition.
But anywho, this thread is about Mueller. Sorry for getting this off topic.
Trumpism is the logical conclusion of the last half a century of the GOP's ideological turn. It stands in the tradition of "Wallaceism" which of course was incorporated by numerous leading Republicans into the party to varying degrees. It is rooted in racial conservatism, status anxiety and the belief that the country is now run by groups that only funnel money to minorities. If you look at comments made at Wallace rallies in 1968 you will find a remarkable similarity to those made in 2016 at Trump events.
Trump is moreover an anti-government populist in a party that's been making the case for over 50 years that more government is always bad, that DC is a cesspool of corrupt politicians and that the people can never be wrong. Of course it was only a matter of time until someone turned the focus on the Republican elite itself - many of whom have been in DC for decades.
