I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Abraham Lincoln vs. Zombies Movie plot: In 1819 Kentucky, after his mother Nancy Lincoln (Rhianna Van Helton), falls victim to an illness that requires her to be tied to her bed, vicious and cannibalistic, 10-year-old Abe Lincoln (Brennen Harper) sees his father Thomas Lincoln (Kent Igleheart) commit suicide at her bedside. Taking up a weapon, the distraught young Abe tells his mother that he loves her before beheading her. He then joins others in his community in containing a local zombie outbreak.In August 1863, when an adult Abraham Lincoln (Bill Oberst Jr.) has become President of a fracturing United States, he is apprised of rumors concerning a prominent Confederate stronghold. He is told that a regiment of 30 men had gone to Confederate Fort Pulaski to seize it from the Confederates and only one man returned barely alive. When questioning the survivor, Lincoln discovers the soldier has an illness that seems to bring corpses back to life. He then personally leads a team of the newly established Secret Service to accompany him in investigating the fort in the Deep South.They get to the fort and are attacked by Confederate survivers led by the one-armed General Thomas 'Stonewall' Jackson (Don McGraw) (who did not die at the battle of Chancelorville but just lost his right arm) as well as by several of the infected people. Abe kills one of his men who had been bitten by an infected and explains to the others in his party that if they are bitten or scratched by an infected, or if an infected's blood makes contact with their mouths or eyes, that they too will become infected and, within 24 hours, would no longer be considered "human". More are lost when attempting to investigate the surrounding neighborhood, and Abe encounters an old flame turned prostitute Mary Owens (Baby Norman) who is sheltering her help, including a young Theodore Roosevelt (Canon Kuipers), to protect them from the invasion.The group makes their way back to the fort where Jackson refuses to kill the infected, believing them to only be sick and in need of care. He claims... My question: Who becomes President of the United States?

Adult Abraham Lincoln
