wouldn't that be Gendry? or do brothers take preference to b*stards?On a side note, to answer your question that I quoted Stannis Baratheon is the rightful King of the 7 Kingdoms. Cersei's kids were fathered by Jaime Lannister. Stannis is the rightful heir. At some point in time, Stannis came to be alongside Melisandre who is practices the religion of R'hollor, the Lord of Light. She sees visions in her fires and sees him as King if he will give himself to the Lord of Light. Stannis has resisted. Thats basically all there is to explain.
