Look at the situation from the old guard's point of view. Numbers wise ( MPs), it's hopeless, the military backed parties are even facing more investigations regarding their MPs' election than MF and PT!

Work on PT.
' You're feeling sore, right? You lost to those young whippersnappers who want to destroy Thailand as we know it, right?
Here's the deal, we vote for Settha as PM, the big boss can come back provides he behaves himself, and PT, along with our boys, vote down any ' troubling' legislation proposed by the upstarts.
What do you say?'
