Uruguay: Vazquez seen favorite in presidential election thanks to strong economy, Mujica

Former president Tabare Vazquez is favored to win Uruguay's runoff election Sunday on the back of a strong economy, a result that would help secure the country's pioneering marijuana laws.

Five polls show the left-leaning Vazquez ahead of center-right challenger Luis Alberto Lacalle Pou by a roughly 10 percentage point margin.

Vazquez took office in 2005 and left in 2010 with high popularity ratings that put his party's candidate, Jose Mujica, in the president's office.

Now Mujica appears set to return the favor as his 70 percent approval rating is boosting Vazquez's candidacy. Both men belong to the Broad Front coalition.
