Qor sii socodka faqradan - Bishii Agoosto 29, 2008, McCain wuxuu shaaca ka qaaday Guddoomiyaha Alaska Sarah Palin inay tahay doorashadiisa lama filaanka ah ee lammaanaha u tartamaya. McCain wuxuu ahaa kaliya musharaxa labaad ee madaxweynaha ee xisbiga ugu weyn Mareykanka (ka dib Walter Mondale, oo doortay Geraldine Ferraro) inuu doorto haweeney inuu noqdo saaxiibkiisa tartanka iyo Jamhuuriga ugu horreeya ee sidaas sameeya. Bishii Sebtember 3, 2008, McCain iyo Palin waxay noqdeen musharixiinta madaxweynaha iyo ku xigeenka xisbiga Jamhuuriga ee Shirweynihii Qaranka ee Jamhuuriga ee 2008
waxaan ku noolahay magaalada Saint Paul, ee gobolka Minnesota. McCain ayaa ka horyimid Obama codbixinta qaranka ka dib shirweynaha, maadaama doorashada Palin ay ku dhiirrigelisay codbixiyayaasha Jamhuuriga ee hore uga digtoonaaday. Si kastaba ha noqotee, ololaha ololaha ayaa markii dambe qirtay, soo bandhigida Palin ee warbaahinta qaranka ayaa si liidata u dhacday, iyo falcelinta codbixiyeyaasha ee Palin ayaa sii kordheysay si xun, gaar ahaan kuwa madaxbanaan iyo codbixiyeyaasha kale ee ka walaacsan aqoonsigeeda.
