Reaganism

A useful heuristic: Be very suspicious of anyone who is firmly entrenched in power but rails against "elites". Reaganism was a political perspective in the United States based on a friendly-seeming, grandfatherly-type ex-actor telling us that government could do no good, and then proceeding to drastically expand the power of the Executive Branch as he saw fit, not to mention exploding the public debt. Why anyone believed it is beyond us.

The only thing Republicans want from a candidate is a pet rock with an A rating from the NRA a working pen hand. That's it. It's what they liked about Reagan and what they thought they were getting in Nixon and GWB: Just some guy to sit in the oval office and shake hands with girl scouts, while the real work was being done in the Republican-controlled Congress. The Speaker sets the agenda, they bring him a big blue folder and a nice black pen, he whips out his autograph and signs that bill into law. The last thing they want is someone with an agenda. But, boy oh boy, did they get Presidents with agendas.

Lies of note
Prominent lies promoted by Mr. Reagan include the following:
 * The "free market" is always more efficient than the government at providing solutions to problems. (See universal health care)
 * The "government" is incapable of solving a country's problems (See Hurricane Katrina)
 * Some woman somewhere on welfare had a Cadillac and a color TV. (He made this up )
 * Hardworking blue collar Americans should hate suffering poor Americans for eating their tax dollars instead of working their asses off for giant corporations themselves. (See trade union)
 * The "rich" are a beleaguered and overtaxed suffering demographic. (Who pay well for political campaigns!)

History
Candidate Nixon ran against Reagan in the '68 Republican race. He won the nomination by running as an outsider, refusing to make any pledges or cut any deals. The day after the 29th Republican Convention, he exposed the deal he made with the southerners to ensure their support in the general election: the appointment of Spiro Agnew as Veep. Agnew was knighted by the southern delegation after he behaved boorishly to the blacks of Baltimore that spring.

In his speech, Nixon condemned LBJ's welfare state, Social Security, and activist judges who supported integrated schools. (As POTUS, Nixon concurred with Goldwater that the Supreme Court was "not, necessarily, the law of the land", though probably in a slightly different way than Barry intended.) Nixon split hairs on the subject of Vietnam: Five months earlier, he had said, "There is no alternative to the continuation of the war"; now he was suddenly talking like a peace candidate, insisting that "the time [had] come for negotiation"; but in case that sounded like appeasement, he quickly reminded everybody that it was "time we started to act like a great nation," whatever that meant. Gore Vidal, who covered the RNC that year, reported with awe:

Part of the reason why Reaganism persists, apart from the fact it works (Nixon was re-elected, as was Reagan and Bush Jr.), is that most of the hacks in his cabinet were awarded positions in later Republican administrations. With Nixon, he initially seemed like a safe bet. He was a "local boy done good", scandal-free, with an impressive track record in getting votes. But then it turned out he’s nuts, too: He nearly brought down the republic, provoked a constitutional crisis and flirted with dictatorship.

The GOP was determined not to make the same mistake again. They picked a retired actor and General Electric spokesman who could convincingly deliver a speech (even if he vomited nonsense whenever the teleprompter was switched off ). Reagan capped his 1988 farewell speech with the classic line, "man is not free unless government is limited." That quote is still a rallying cry for conservatives, but the speech followed eight years of government expansion: not only did the federal workforce double under Reagan, the national debt was tripled.

Bush II fits the bill because he is an imperious, incurious, pseudo-cowboy idiot, with a profound need not to know, and as such he was easily bamboozled by Cheney, Rumsfield, Wolfowitz, Rove, Rice, Kristol, Feith, and several others. More government overreach and debt ensued.

Today's usage
When Trump says he's going to "repeal and replace Obamacare" — that's Trump's "Born To Run" — the crowd roars appreciatively. Getting rid of Common Core is Trump's "Thunder Road"...Recently, Trump has taken to yelling, "Who's gonna pay for the wall?" Crowds respond enthusiastically, "Mexico!"

Today's Republicans reflexively use this strategy all the time. In fact, the entire field of GOP 2016 candidates for President (minus Rand Paul) are entirely absent of ideas, instead expressing a wish to dismantle or repeal this or that; or in Trump's case, bald-faced lies and pie-in-the-sky promises that not even a two-term President could back up in reality, much less a newcomer with zero political capital. They're all sizzle and no steak — just the type that incurious, low-information Tea Partiers and Libertarians will vote for.

You must admit he's getting some serious mileage out of essentially yelling, "It'll be so good, your head will spin", "I'm smart", I'm rich," and "I'm Donald fucking Trump". The only thing he hasn't lied about was his family. Like, presumably that really is his wife and his kids. Those would be statements of fact. (Naturally his attraction to his daughter would also be something factual.) Beyond that, it seems like everyone falls silent if he breaks his promises, then revises their political opinions when Trump speaks about an issue. It's a weirdo cult of personality: let Trump shoot the arrow first and paint a bullseye around it afterward.

In the UK
In Britain, there was a very similar political movement referred to as "Thatcherism," named for the Iron Lady who advocated the same principles. The impact of this was slightly less fun that of the States. Anti-establishment politicians are rising everywhere, usually by railing against an elite establishment, such as 'Westminster elites' or 'Washington elites'. In Britain, politicians have managed to point to an even higher, more shadowy elite in Brussels, allowing the strange situation where Eton-educated Boris Johnson and millionaire banker Zac Goldsmith can paint themselves as anti-elite. The tolerance of UK voters for the character pitfalls of current Prime Minister Boris Johnson clearly falls into this category. Evidence of his frequent lying, sackings, incompetence, laziness, hypocrisy, corruption, croneyism and numerous (but unknown number of) children conceived in and out of wedlock - conclusive evidence that he has never understood the concept of withdrawal (including his cocked-up attempt at Brexit) - yet remains, for the time being, surprisingly popular among a generally conservative and moralistic but passive electorate.
