Thursday's protests come about a week after Argentinian lawmakers passed a new measure lowering the nation's voting age from 18 to 16. Some critics have said the voting-age change, a year before a key mid-term election in Argentina, is an attempt by Fernandez's party to garner more votes and increase the odds that lawmakers will change the constitution to allow her re-election bid.
Many demonstrators Thursday said they would oppose such a move.
"The constitution should be respected, not be reformed," said Francisco Bugallo, who helped organize the Buenos Aires protest.
Rosendo Fraga, a political analyst based in Buenos Aires, said that the cacerolazo protests will affect the country's political future.
"They will without a doubt influence the mid-term elections. ... There's a lot of time before those elections," he said, "but this gives the opposition an opportunity."
