Leftist candidates lead as Guatemala heads to divisive run-off election.

Guatemala's presidential election is headed for a run-off in August, with early results showing the center-left in the lead but also indicating widespread voter frustration over the exclusion of an early favorite. Leading candidate Sandra Torres is on track to fall well short of the 50% plus one vote needed for outright victory. The election has been dominated by international concern over corruption, and the exclusion of businessman Carlos Pineda has been criticized by the US and the EU. The stakes are high given deteriorating standards of transparency and human rights in recent years, as well as poverty, corruption, and violence.
