Runoff voting for freshman class officers ended Thursday night, and results were announced Sunday.
Grant Gittlin defeated Aaron Spolin for president, having received 310 votes to Spolin's 251.
The vice president, treasurer and secretary were also elected in the second round of voting.
Katie Lawrence and Arjun Reddy faced-off for vice president. Lawrence won the post with 296 votes to Reddy's 248.
Treasurer candidates John Curtius and Kyle Super went into the runoff, and Super won the election with 285 votes to Curtius' 235.
Sarah Breslow and Meaghan Petersack vied for secretary. Petersack won by a margin of 37 votes.
A total of 30 students ran for Class of 2008 officer positions — president, vice president, treasurer, secretary and social chair.
"I was thrilled to see so many candidates running and to have such a high voter turnout," USG president Matt Margolin '05 said.
According to USG rules, elections are only won when a candidate receives a majority of votes cast. With such a large number of candiates for each position — 12 for president, nine for vice president, four for treasurer, three for secretary and two for social chair — four of the five contests needed a runoff. The race for social chair was the only position decided in the first round with Regina Yang defeating Lola Adekunle.
Runoffs included only the top two voter-getters from the first round.
"I am so excited about winning the position of freshman class president. I can't wait to make a difference in the lives of every member of the class of 2008 and make this year as amazing as possible," Gittlin said.
Spolin said that it was "disappointing" to lose the election but added, "I think [Gittlin is] a good guy and that he'll do a good job."

Candidates almost universally guaranteed to organize contests, concerts and trips.
Many candidates' statements also included promises to expand the late meal program at Frist Campus Center.
The freshman class officers — Gittlin, Lawrence, Super, Petersack and Yang — now have the formidable task of fulfilling their campaign promises and attempting to convince members of the Class of 2008 to reelect their officers.
