On 28 May 2012, protesters angry at Shafik's advancement to the second round of voting set fire to an office associated with his campaign in Cairo. Fellow candidate Khaled Ali said while participating in a protest against the election results in Tahrir Square that Tahrir had "toppled Mubarak, and would topple Shafik". The election contest between Shafik and Morsi had been described as a "choice between two of Egypt's most polarizing politicians", and some activists resorted to participation in a hunger strike to protest his candidacy.
