Why am I not surprised?
Still, opposition would have to go a very long way to invalidate the election outcome or force a new election. If they are lucky, maybe they will gain a few more MP seats, but I don't foresee anything more than that or anything that could prevent Anutin from becoming the Prime Minister, along with his political party in the clear majority.
I really have difficulty understanding what good they think complaints are going to do, even if the flaws, corruption, vote buying, and everything else proves to be valid. Like it or not, the People's Party clearly lost and the Bhumjaithai Party clearly won. I truly believe the will of the people should prevail. I think the People's Party would do much better to amicably accept the results and try to work cooperatively with their opposition in a positive way so that at least some of their goals might have a chance to be met.
