Despite a 70 percent voter turnout and 1,401 ballots cast, there were no lines at the polls in Cotter Union when Student Government Association elections were held April 8. Voting was conducted exclusively on the Internet as Colby students participated in the first paperless election in the College's 185-year history.     Students could vote from any computer on the campus's local network, whether in their dorm rooms or public computer clusters. Students abroad this semester had to vote by proxy since the ballot was not on a Web page visible from outside the campus network. A code was used to ensure that eligible students could vote only once.     In the top race, Benjamin Langille '99 of Lawrenceville, N.J., and running mate Braden Sicchitano '99 of Wellesley, Mass., won the race for SGA president and vice president.     The SGA's online election was held the same week that Yahoo! Internet Life magazine announced that Colby is, once again, one of "America's 100 Most-Wired Colleges."
