olivians have begun casting ballots in elections to pick a new president, vice president and Congress.
Public opinion polls show presidential candidate Evo Morales with a slight lead heading into Sunday's vote. If elected, he would become the country's first indigenous president.
The leftist coca farmer has said he would reverse efforts to eradicate coca fields and increase government control of the country's natural gas resources.
Close behind in the polls is Jorge Quiroga, a conservative former president who advocates free market policies.
Neither candidate is expected to receive a majority of the vote. In that circumstance, Bolivia's newly elected Congress will choose between the two leading contenders.
The vote is being monitored by international observers and some 50-thousand police and security personnel.
