Peru¡¯s presidential race remained wide open on Monday, with roughly half the ballots still uncounted after a second day of extended voting, leaving conservative Keiko Fujimori in the lead but no clear challenger for a ?likely June runoff.

A tight race for Fujimori's second-place challenger started to take shape, with right-leaning?former Lima Mayor Rafael Lopez Aliaga, center-left candidate Jorge ?Nieto, ?and outsider Ricardo Belmont clustered within a narrow band. Each was polling between 10%-14%, with just under 60% of ballots ?counted.

Long lines persisted outside polling stations in parts of Lima during the day as voters returned to cast votes for president and a new bicameral Congress after widespread delays hampered Sunday¡¯s general election.
