BUENOS AIRES (Reuters) - Argentina's fiery former President Cristina Fernandez formally launched her bid on Saturday for a Senate seat in October's mid-term elections in a race that will determine whether President Mauricio Macri can deepen his free-market reforms.
Fernandez' run, confirmed by a spokesman, comes a little over a week after she formed a new centre-left party independent of Peronism, the Argentina's dominant political movement that she has belonged to for decades.
