The problem is that many people will not vote for Pheu Thai as long as the Shinawatras are involved. If he kept his mouth shut and kept his family away from this party, I believe they would win even more votes/seats. The party introduced some good policies and gave people of the North and North East their voice (probably to support his party rather than any real concerns for the people, but that seems to be the norm in Thai politics), and is recognized for this. Even so, I know I will not vote for this party as long as the Shins are involved, no matter how good their policies are.
