SAO PAULO (AP) — The Latest on Brazil's presidential runoff (all times local):

10:20 a.m.

Voting for the presidency is in full swing in Latin America's largest nation.

Voters are picking between far-right Congressman Jair Bolsonaro and former Sao Paulo Mayor Fernando Haddad.

Polls ahead of Sunday's vote showed Bolsonaro with a 10 percent advantage. Still, the race appeared to be tightening, as just weeks before Bolsonaro had an 18-point lead.

Bolsonaro cast his vote in Rio de Janeiro, which he represents in Congress. Haddad was expected to vote later Sunday in Sao Paulo.

During the first round of voting on Oct. 7, Bolsonaro garnered 46 percent compared to 29 percent for Haddad.

Bolsonaro has promised to crack down on crime and overhaul the economy. Haddad has promised a continuation of many progressive policies of his Workers' Party, which governed from 2003 to 2016.
