Fernandez's husband, President Nestor Kirchner, is credited with Argentina's rebound from a 2001 economic collapse, and much of her support is due to his popularity.
She has been compared to Sen. Hillary Rodham Clinton, who like her is a lawyer and senator who soldiered alongside a husband as he rose from small-state governor to the presidency.
"We have won amply," she proclaimed, Kirchner standing at her side. "But this, far from putting us in a position of privilege, puts us instead in a position of greater responsibilities and obligations."
Her challengers were trying to force her into a Nov. 25 runoff. She needed 40 percent of the vote, with a lead of more than 10 percent over her nearest rival, to win outright.

Six independent television networks, a private radio station and an opposition newspaper reported their exit polling indicated Fernandez has easily won a first-round victory. Five of the news organizations released their numbers, giving Fernandez between 42 and 46 percent of the vote, with advantages of 19 to 23 percentage points over Carrio.
