A new public opinion poll shows that a leftist economist seeking to become Ecuador's next president is essentially tied with his main rival, a former vice president.

A poll released by Cedatos Gallup on Tuesday shows that Rafael Correa has gained two points to hold 19 percent of voter support ahead of the October 15 presidential election. The former economy minister has worried foreign investors with a proposal to restructure Ecuador's foreign debt payments.

He is slightly behind Leon Roldos, a left-leaning former vice president who dropped two points to 20 percent in the opinion poll.

Conservative Cynthia Viteri is in third, with 13 percent support in the poll. Almost half of all voters remain undecided.

If no candidate wins 50 percent of the ballot, a run-off will be held between the two top candidates in November.

The poll reflects the opinions of 3,342 people surveyed from Friday to Sunday. The margin of error is three percentage points.
