Polling places have opened for Argentina's presidential election and already some politicians have showed up to cast votes.

Government-backed candidate Daniel Scioli had to struggle through a crowd of journalists to reach a ballot box in Buenos Aires, the capital. The 58-year-old was accompanied by his wife and daughter.

Most polls show trends favor his rival, Buenos Aires Mayor Mauricio Macri.

Scioli stresses continuation of the government's extensive welfare programs and subsidies. Macri says he'll keep key welfare programs but will put greater effort into reviving the economy.
