According to an opinion poll published Friday in the Delo daily, Pahor will win about 55 percent of the vote, while Turk will garner 24 percent. The poll was conducted among 780 people with a 2.5 percent margin of error.
Pahor told the AP on Friday that the protests "signal a lack of confidence" in government institutions.
"It is important that by not using force we give people hope that all problems can be solved," he said.
The 49-year-old has supported some of the government's reform measures, unlike current president Turk, who has been a fierce critic.____ Jovana Gec in Belgrade, Serbia, and Amer Cohadzic and Eldar Emric in Ljubljana contributed to this report.
