Carlos Reutemann led the race against Giustiniani by only 2 percent of votes. "I fought against everything and everyone," Reutemann said.

Santa Fe Province, Argentina's fourth largest, has 2,375,271 voters for the legislative elections, making up 8.5% of the electoral roll.

Santa Fe Province is voting 3 senators and 9 national deputies. Two senators will be for the majority and the remaining for the first minority.

The Santa Fe elections could be a key in the national vote, as Socialist Governor Hermes Binner and National Senator Reutemann already said they are planning to run in the 2011 presidential race.
