 According to political scientist Duncan McCargo, "most appointed senators are broadly in the pro-Democrat camp" which is opposed to the acting government of Prime Minister Yingluck Shinawatra.A local think tank, the Siam Intelligence Unit, estimates that 90% of the appointed senators are anti-government.Elected senators must be independent from political parties, with no immediate relatives in parliament and must not have been a member of a political party in the last 5 years.
