Argentines are heading to the polls in an election that centre-left President Cristina Fernandez is expected to win.
Polls show Fernandez taking a landslide victory on Sunday, with enough votes to avoid a run-off.
The 58-year-old leader has seen the country’s economy grow by eight per cent annually.
In the August primary the sharp-tongued former senator won more than 50 per cent of the vote which served as a giant opinion poll.
To win Fernandez needs at least 45 per cent of the vote or just 40 per cent with a lead of 10 percentage points over her closest rival.
She vows to dedicate her second term to her husband Nestor Kirchner who preceded her as president. He died in 2010.
