Well team Stannis seems pretty common to me, but I don't have any data to back that upViewers want to see Stannis succeed? I think he's a little... to tempted to kill his daughter and do crazy shit with the red temptress. I don't trust Littlefinger and him being on Stannis' side makes sense.
I'm pro Tyrion, Jon, and Daenerys as leaders and being successful. I think Jon would support Danerys over Stannis as well.
I think now especially because he's gonna take the North and in theory give it to a Stark, people are turning around.
