The results of Argentina's legislative elections will give President Mauricio Macri the increased support he needs to move forward on controversial economic reforms, but he still might not have the support he needs to actually pass some of the reforms. On Oct. 22, Macri's ruling coalition, Cambiemos, increased its number of seats in both houses of Congress. In the 257-seat lower house, Cambiemos gained 20 seats for a total 107 seats. In the 72-seat Senate, Cambiemos gained six seats for a total 24 seats. Despite being the largest coalition in both Congressional houses, Cambiemos does not have a majority of seats and will likely encounter resistance to its reform proposals. The second largest political force in the lower house, led by allies of former President Cristina Fernandez de Kirchner , has 67 seats in the lower house.
