Calderon calls for unity following elections

Mexico’s main leftist candidate plans to challenge the presidential vote tally at tens of thousands of polling places, and also will allege that attack ads by the apparently victorious conservative were illegally harsh, a top adviser said today.

The comments came a day after ruling-party candidate Felipe Calderon, who came out almost 244,000 votes ahead in yesterday’s official count, urged Mexicans to leave the bitter election campaign behind and work for unity.
