Waa kuwee madaxweynayaasha ugu sareeya Mareykanka
Abraham Lincoln, Franklin D. Roosevelt, iyo George Washington ayaa inta badan ku taxan seddexda madaxweyne ee ugu qiimeynta badan taariikhyahannada. Madaxweynayaashii ugu dambeeyay sida Ronald Reagan iyo Bill Clinton ayaa inta badan lagu qiimeeyaa kuwa ugu weyn ee ra'yi ururinta dadweynaha, laakiin guud ahaan uma kala sareeyaan aqoonyahannada madaxweynaha iyo taariikhyahanada. Sababtoo ah William Henry Harrison iyo James A. Garfield labaduba waxay dhinteen sanadkoodii ugu horreeyay ee xafiiska, badanaa waa laga saaraa darajooyinka madaxweynaha. Zachary Taylor wuxuu dhintay kadib markii uu madaxweyne ahaa 16 bilood oo kaliya, laakin waxaa lagu daray inta badan. Saddexdaas madaxweyne, ma cadda in ay heleen qiimeyn hoose sababo la xiriira ficilladooda madaxweyne ama sababtoo ah mid waliba wuxuu xafiiska joogay waqti xaddidan oo aysan wax badan qaban.
