I’m younger than the lower limit of your age range, but I’m a liberal by US standards so I’ll chime in anyway.
I never thought that I would look back with nostalgia at the Reagan presidency (not that I do in absolute terms, but by comparison…). 1980 is the earliest I can remember following US Presidential elections, and I first visited the US when Reagan was POTUS. The current administration makes the worst aspects of the Reagan years look like the work of a bunch of amateurs. Of course, in many cases it’s the same people involved – they’ve just honed their skills.
The person who is in the absolute best position to answer the OP’s question, but who would be unlikely to give an honest answer, is GWB’s father, the 41st President, GHW Bush. Although I had never set foot in the US at the time, I remember his primary campaign against Reagan, during which he was the person who first called Reagan on his “Voodoo Economics”. However, when Reagan won the primaries and offered GHWB the Veep spot, he had to knuckle under to the “Reagonomic” ideals. I’ve often wondered what he must have been privately thinking about his boss during those years.
Now, we have GHWB’s son in the White House, but the administration is much more “Reagan redux” than “GHWB redux” (although IMHO it’s much worse than the Reagan presidency). Many of what I think of as the better characteristics of GHW Bush (personal bravery, a certain integrity pre-1980, reluctance to bow to the religious right, preference for diplomacy over rash military adventure, respect for the UN) are essentially mocked by his son’s actions.
I actually feel quite sorry for George HW and Barbara Bush. I can’t imagine that they’re happy with the road down which their son is taking the US, and the world.
In 1988, I sincerely hoped that Reagan would be the worst US President that I would see in my lifetime. With hindsight, that’s turned out not to be the case, but I at least hope that the world will never see a POTUS worse than GWB.
