Candidates for Congress Francisco de Narvaez (L) and Gabriela Michetti (R) pose for a picture with Argentine television hostess Mirta Legrand during her show in Buenos Aires, June 25, 2009. De Narvaez, a millionaire businessman who leads a congressional ticket of a dissident faction from the ruling Peronist party, will challenge the government in the country's biggest electoral battleground, the province of Buenos Aires, and is likely to face off with former President Nestor Kirchner in the June 28 balloting that will determine if Argentina's President Cristina Fernandez de Kirchner keeps her majority in Congress.
