Nowadays, everyone in the house of lords have noticed that Geoffrey has become different. Although there was slight resentment initially towards him because of him mentioning the orphanages, which led to some nobles getting milked (getting money from them), they all have seen the way he handled it, and it touched the heart of many.
He was diligent, charismatic, promising, and most of all, he has a heart. All these makes him very fit to be the future king, making his popularity soar in the circle.
