The Neocons were former Democrats, as was Reagan, and as such were in opposition with the Old Right, the New Right, the Libertarians.
Reagan favored the Neocons and their form of a somewhat ‘new’ Conservatism that rose out of their departure from the Democrat Party, much like Reagan’s own departure. Irving Kristol, Bill Kristol’s father, was part of the Liberals-turned-Conservative, as was Bill Bennett.
Donald Trump is being critiqued in much the same manner as Reagan was. But Reagan didn’t let it deter him from his plan to make America great again.
Reagan courted the Neocons during his 1980 Presidential campaign . . and subsequently recruited many of them into his administration.
When anyone applauds the Presidency of Ronald Reagan and yet degrades Trump for being ‘too liberal’ . . perhaps they should read the real story behind Reagan’s campaign and administration and see for themselves how Trump closely resembles Ronald Reagan.

Only two criticisms of Reagan at your link - and only one of them is from the right - and it falls miles short of your claim that "hard-nosed Conservatives accused [Reagan] of having a Democrat agenda when he was running for Prez" and of the multifaceted conservative criticisms of Trup.
"Kristol thought the Reagan administration was too harsh on the welfare state. Leading the most avid cold warriors, Podhoretz denied that the Soviet Union was becoming more democratic in the late 1980s and chided Reagan for pursuing detente in fact if not in name."
