The President of the Plurinational State of Bolivia or President of Bolivia , is head of state and head of government of Bolivia. According to the current Constitution, the president is elected by popular vote to a five-year term, renewable once. Prior to the 2009 constitutional reforms, if no candidate received half the popular vote, the president was chosen by a vote in a joint legislative session from among the top two candidates (prior to 1995, the top three candidates were eligible). The 2009 constitution introduced a second-round runoff election.
