Anti-government protesters have rallied again in Argentina's capital Buenos Aires. They are opposed to President Cristina Kirchner's policies that affect inflation, crime and freedom of the press. Kirchner's supporters say the protests are organised by the wealthy and the country's conservative media. There have been few poor people marching against the president. That's because they remain a strong part of Kirchner's political base. From Buenos Aires, Al Jazeera's Teresa Bo explains why.
