Incumbent governor Axel Kicillof, of Union for the Homeland (UP), was re-elected to a second term with 44.88% of the vote. Analysts pointed to Kicillof's successful re-election bid as a major factor in bolstering the shock victory of UP presidential hopeful Sergio Massa in the first round of the country's presidential elections.^[3][4]
