Georgians cast their ballots at a polling station in Tbilisi, Georgia, Saturday. They were voting in a presidential election to determine whether their country will continue to be led by Mikhail Saakashvili, the brash young president who four years ago set out to transform the bankrupt former Soviet republic into a modern European state. Saakashvili's supporters celebrated in the capital after exit polls showed him winning 53.8 percent of the vote. But the poll had a margin of error of plus or minus 3 percentage points — casting doubt on whether the president would hang onto the absolute majority needed to avoid a runoff. The opposition called for protests today, claiming the vote was rigged. However, an international election monitoring mission said that the election appeared fair.
