A Tucson author who is a native of Egypt says the people of her home country will have clear choices when they go to the polls this week to elect a new president.

Laila Abou-Saif, who has written books and articles about the region, says the citizens can choose from among candidates who would be considered moderate secular leaders in the Western world and others who would move Egypt much more to the right, with a stronger connection and affiliation to Islam than in the past.

Abou-Saif says the outcome will have a significant impact on Egypt's society and which way the country's regional influence will tilt.

"Society might change gradually like a chameleon but change to close itself from the West and particularly from the United States," Abou-Saif says.

After its own Arab Spring in 2011, Egypt will hold elections for president this week -- Wednesday and Thursday.

Thirteen candidates are vying to replace ousted president Hosni Mubarak and lead the nation of more than 80 million people.

If no one wins more than 50 percent of the vote, a run-off election is scheduled to take place on June 16 and 17.
