It's what a politician's hands become when they are suddenly thrust into the spotlight. It takes some serious time to polish and groom this look as they feel that keeping their hands together at chest level, whilst gesticulating, makes us citizens feel that they are more trustworthy. Behind closed doors, they're hands return to their normal function.
Damn! That candidate looks like he's the real deal! I can tell because his Politic Hands show me that he would never steer us wrong!
