Thursday is the last day of campaigning in Libya's first democratic elections in more than 40 years. Libyans will cast their vote at the ballot boxes on Saturday. They will choose among more than 25-hundred candidates that are standing for 200 seats available in the General National Congress. Adding to the nervous anticipation is the fact that there are no opinion polls in Libyan politics, none of the parties know exactly how effective their campaigning has been.
