Ecuador's President Rafael Correa has won re-election but may have little time to savor the decisive victory. The leftist economist must now determine how to maintain his ample social spending programs in a deepening economic crisis.

Correa won 51.2 percent of the vote in an eight-candidate field, according to official results April 27, with 70 percent of ballots tallied, making him the first Ecuadorean president elected in 30 years without a runoff.

Exit polls indicated Correa's Alianza Pais party and allies won a majority in the new congress.

Correa, a youthful U.S.- and Belgian-trained former academic, vowed upon first taking office in January 2007 to rid the small, traditionally unstable Andean nation of a corrupt political class that had for decades siphoned off oil wealth.

The April 26 elections were mandated under a new constitution voters approved in September that, in addition to giving Correa greater control over spending and the central bank, makes him eligible to run in 2013 for another four-year term.
