Trump is the opposite of Goldwater politically. Trump is a statist, and Goldwater was a libertarian.
Someone once pointed out that Goldwater stood at the head of both "branches" of modern conservative, the social conservatives (Christian conservatives, Moral Majority, also Christian Identity and similar ethnic-identity and/or racist fringe groups like VDARE, Covenanters, etc.) and the libertarian conservatives (Paulbots, marketarian or economic conservatives [19th-century liberals and ordoliberals], and land-use and tax-resistance groups).
All these groups can point back to Senator Goldwater and hils conservative movement, who were the Main Street Republicans who'd fought with the Gilded Age plutocracy (the "Stalwarts") since the 1880's -- and been derided for their troubles as "Mugwumps" and "Bull Moosers" for generations before they rallied around Bob Taft and then Barry Goldwater against the "Me-Too'ers" and "good government Republicans". The latter were Bush-era "moderates"/"economic conservatives" who were at pains to distinguish themselves from the "socons" whom the Bush family have always derided and despised as barely-disguised KKK kleagles, n/w/s that they had before their disbelieving eyes two of the biggest, both Democrats, sitting on the Supreme Court and in the Senate Majority Leader's office back in the 1970's.
But Manor Bush is part of the old "Stalwarts" who started and won the Civil War to protect Yankee political power for a time and to aggrandize the newly risen manufacturing and financial moguls and their managerial-class hangers-on (like the infamous Henry Clay Frick, who liked to break strikes by breaking faces and shooting people, and his successor in infamy, "Chainsaw Al" Dunlap, the modern "turnaround specialist").
Therefore the "economic conservatives" are not and have never been "conservative" in the sense of "classical liberals", but rather the access-capitalist class against whom classical liberalism was a reaction: against permanent class advantage, structural advantage, privilege, classism, statism, fascism, and all that went with them.
