Although the No.12 single-mandate constituency was established for four of Ukraine's parliamentary elections, this area is represented by the No.12 territorial constituency for presidential elections, as was the case in 1999, 2004, 2010, and 2014. The territory of this constituency is quite larger and different in its boundaries, representing the province's Vinnytsia Raion (district), and the Zamostianskyi Raion of the city of Vinnytsia itself. Accordingly, this presidential election constituency voted for President Leonid Kuchma in 1999, President Viktor Yushchenko in 2004, front-runner Prime Minister Yulia Tymoshenko in 2010, and President Poroshenko himself in 2014.
