Although family members of caretaker Education Minister Chaturon Chaisang managed to achieve enough votes to win seats in the election, the number of votes they received were exceeded by the combined number of "no-vote" and invalid ballots.

In Constituency 1, Thitima Chaisang received 38,372 votes, while "no vote" ballots numbered 33,879 and invalid ballots 9,717 - a combined total of 43,614.

Thitima received 33.17 per cent of the total 115,676 eligible votes, with around 70 per cent, or 81,986 voters turning out to vote in her constituency.

As well as the "no vote" ballots there were an exceptionally large number of invalid ballots, as voters deliberately spoiled their ballots in a statement of their dissatisfaction with the ruling Thai Rak Thai Party and Prime Minister Thaksin Shinawatra in particular.

In Constituency 4, the situation was similar. Vuthiphong Chaisang received 40,606 votes, compared with 31,327 "no vote" ballots and 11,289 invalid ballots, a combined total of 42,616, exceeding Vuthiphong's votes by over 2000. However, Vuthiphong still received 33.58 per cent of the total 120,905 eligible votes.

The total voter turnout in this one-horse-race constituency was 68.83 per cent with a total of 83,222 of the constituency's electorate turning up to cast their votes.

In Constituency 2, Somchai Asawachaisophon received 40,953 votes, while the "no vote" and invalid ballot totals were 27,632 and 12,456, respectively. He won by a thin margin, with just 865 votes more than the combined number of "no vote" and invalid ballots.

In Constituency 3, Suchart Tancharoen proved more successful, receiving 51,255 votes, well exceeding the 15,725 "no vote" and 12,102 invalid ballots. Chukiat Rjanaphinand, the governor of Chachoengsao, said the voter turnout in the eastern province was comparatively high at 76 per cent. The high number of invalid ballots, which was between 10-16 per cent in all constituencies, was also notable. "It was obviously an intentional move," Chukiat said.
