Game of thrones casting politicians

Just to have some fun I thought who would be the best politicians to fit the characters of GOT.So I'll throw out a few,just let's not make this a Trump good or Trump bad thread,Ok,first one Samwell Tarley- has to be Lindsey Graham for finally getting a backbone of sorts.King Robert - Trump.Should have seen it coming.Cersei Lannister,no question,Nancy Pelosi has no competition .Jon Snow..hard to cast but Rand Paul because he does always try to dutifully follow the constitution.And Walder Frey,old,feeble man..Joe Biden Danaerys ,AOC,crazy,both of them.Plenty more to go and sure others would be good choices.
