The Democrats also developed a populist agenda, promising more jobs, free education and health care, and combating crime and corruption.
Abhisit Vejjajiva, Banyat's successor, said: "It will take a long time to revive the party because we need to look four years ahead and consider how to stay in the hearts of the people."
A coalition of other parties and civil society groups was formed to prevent this, arguing that Thaksin already had too much power and that giving him an absolute parliamentary majority would encourage what they alleged were his authoritarian tendencies.
Prominent academic Kasem Sirisamphan, for example, accused Thaksin of running a "parliamentary dictatorship" and said that "people do not want a billionaire prime minister to further dominate the country and its politics."
The deaths of Muslim protesters in southern Thailand and the bird flu outbreak were seen as issues which the Thaksin government had handled poorly.
The tsunami and its aftermath drove the election campaign to a large extent out of the media, and also produced a strong sense of national solidarity, from both of which an incumbent government could be expected to benefit.
"The Democrats might cry foul that Mr Thaksin is using the state media for campaign purposes," Veera wrote, "but the people may think otherwise."
The Bangkok newspaper The Nation said that Thaksin "has apparently won the strongest popular re-endorsement in Thai political history and is set to be the most powerful prime minister ever elected to lead the Kingdom."
This was taken as a reference to the situation in the south of the country, which has a large Muslim population, where there has been a history of unrest and disturbances, and where Thaksin's party won only one seat.
The Nation newspaper reported: "Many voters [in the south] said they had lost faith in Thaksin, who has refused to apologise for incidents such as the deaths of 78 Muslims in October who were held in military custody after being arrested for protesting in the village of Tak Bai."
