I've lived in rural Central Thailand for 20 years and, from time to time, engage rural Thais (lower- and middle-class) in political discussion. Before that I worked at a Thai University and for a Bangkok computer company. From my vantage, framing Thai politics as "populists" versus "elites" is over-simplified to the point of falsity.
Unfortunately, any brief comments I might make will also be over-simplified. Rather than making a detailed argument, I'll just make a few terse claims.
Corruption is endemic in Thailand and takes many forms, from low-level "greasing" to gigantic frauds at the highest levels. I've noticed much improvement during my years here. But Thaksin has used his connections (in the 1990s) or direct government control (in the 2000's) to steal huge sums from the Treasury.
Is it a "populist" program to line one's pocket with funds intended for rural development? Many powerful Thai politicians are corrupt, but some seem much worse than others. The most blatantly corrupt, the Provincial Mafia chiefs, are mostly allied with Thaksin's coalition.
Many political parties in Thailand are not about "ideological platforms" but about geography. The "party platform" is, in effect, "We want to divert national resources to businesses and provinces controlled by Godfather So_and_so."
The first military coup I lived through was in 1991, against a government called the "Buffet government" -- Ministers wandered about nibbling on whatever looked good. A later coup was against a "Fast Food government." Horrid as it sounds to most Westerners, there's a case that the Army intervention plays a useful check-balance role to guard against excesses of these "democratically elected" governments.
It is true that Thaksin and his allies win elections. But many voters are naive. Moreover, where I live
voters are paid by candidates in almost every election, usually $10 or more, a day's wages. Think of what the elected candidate must have to do to recover that spending! Money politics doesn't stop there; money changes hands between politicians; and major concessions are made to coalition partners.
Where I live, many people are naive or very close-mouthed about politics. Lower-income women who supported Thaksin most frequently praise
not his populist programs (30-baht, million-baht) but his
War on Drugs. Methamphetamine was a
huge problem here in the 1990's. But if you read details about Thaksin's War on Drugs, e.g. the "extrajudicial executions," you may withhold praise.
Among rural middle-class, it is the
politically connected who tend to support the red-shirt side. Teachers and university students often oppose Thaksin. As I say, Thais are close-mouthed about politics so it's hard for me to "take a survey", but recently I asked a University student what she and her friends thought about the coup. She was silent, but her father (an important local merchant, though hardly "elite") interrupted to loudly declaim that the cycle of corruption needed to be broken before democratic elections could be held.
In the past Thai politics seemed farcical, with thugs playing off against each other. But the wholesale corruption and incompetence of Thaksin and his sister is something new. And they've armed and financed a significant private army, the red-shirt terrorists. Violence may be a real threat.
I have absolutely no ties to the region, but I did lol a bit at the "we aren't staging a coup" statement followed by "we're staging a coup" a few days later when the military did in fact take over. At least it was a bloodless coup. It is...eerie...to learn that the Thai population isn't reacting over this.
The Thais coined a new word:
รัฐประหารแบบนุ่มนวล -- 'delicate coup d'état.' Give the Generals credit for a slow-motion coup that avoided immediate violence.
The Thais are used to coups and -- silly as it will sound to many Westerners -- often appreciate Army intervention as playing a check-and-balance role.
