Attachai Ueranantasun

Abstract
This study examines recent Thailand’s national election on the last three occasions – 2005, 2007, and 2011. The voting results are analyzed and thematic maps, using a variable scale to clarify dense data plots, for the whole of Thailand are produced to display the majority vote in each province and coloured points representing winning candidates. The graphical results show that the number of winning candidates coincides with the percentage of majority votes in almost all provinces. The results from the 2007 and 2011elections illustrate that there is a clear split between the North-East and the South-West, indicating the main competition of two major parties. The vote swings are estimated from 2005 to 2007 and 2007 to 2011, using a simple statistical analysis to distribute gainloss proportion in the form of bubble plots. It shows that minor parties, gained benefit from the political turmoil in 2007, but lost their significant votes in 2011.
