Wall Street's hedge funds can't wait for Argentina's next president.

They've been battling with the current president, Cristina Fernandez de Kirchner, and her predecessor and late husband, Nestor, for 12 years over huge debt payments. That could soon change.

Argentines will elect a new president on Sunday, and a major issue is whether the new leader will finally end the country's fight against New York hedge funds.

After defaulting on $95 billion of debt in 2001, the country has been in a decade-long fight in courts with the hedge funds, also known as "vultures" in Argentina, South America's second-largest economy.

The unresolved debt debacle has shut out Argentina from much of the global economy while it has suffered from massive inflation, declining cash reserves and meager economic growth.

There are three candidates running for president: Daniel Scioli, Mauricio Macri and Sergio Massa. Scioli is most similar to the current president and he's leading in the polls.
