None of those candidates "leaned to the right." Richard Nixon was (his criminality aside) the most liberal president we've had since Franklin Roosevelt. I say that even comparing him to his predecessor. LBJ was progressive on social issues, but he also got us into Vietnam, while Nixon (eventually) got us out of it. Nixon recognized China, got a big arms-control treaty and improved relations with the USSR, and signed the Environmental Protection Act. He pushed civil rights legislation and regulations strongly (back then the GOP was still the main civil rights party and had only just begun to court the white South).
I wasn't speaking of how they governed, but how they campaigned. There was a lot of conservative stuff under Nixon that conservatives were happy about, and he ran against the Hippies for all intents and purposes. Especially in 1972, when the Democrats ran on Abortion, Acid and Amnesty. Nixon won 42 states.
Were you actually there for the 1980 campaign. because I was, and it was a lot different from that bullshit. Reagan ran as an unapologetic conservative. So much so, that the GOP insisted on saddling him with Bush-41.
Sorry, when did he do that? My biggest complaint with Bush was that he ran on the "Compassionate Conservative" label, which was kind of silly. But he clearly stood for stronger national defense, tax cuts, less regulation and traditional values. That last part being important when you had a guy who had just admitted to having sex with interns in his office.
If you want to look at what happens when the Republicans nominate a real fire-eating right-winger (perceived as such) for president, look at 1964.
The very fact you have to go back to 1964 says a lot.
Liberal Republicans always whine about 1964, like Rockerfeller could have really done any better with his "Me, Too!" version. In 1964, we were at peace, the economy was booming, unemployment was non-existant, and LBJ had the fortune of running under the mantle of a martyred president.
But whenever the Beltway Establishment wants to push losers on us, and not stand up for principles, they first thing they scream is "Goldwater". Ignore our four moderate LOSERS since, we are going to keep going back 50 years to find when a "conservative" lost.
