The online polls are open from 7 a.m. until 10 p.m. today on Student Central.
Last week some seniors couldn't vote because they were listed as juniors by the voting software, allowing them to vote for UNC's Homecoming king and queen but not for the senior class gift.
Although the problem was fixed by roughly 9 a.m., Board of Elections officials decided to reschedule the vote because seniors who voted earlier in the morning could not vote a second time.
Senior Class President Paymon Rouhanifard said a smaller turnout is expected today because the vote for Homecoming king and queen will not be included.
But he said such a small turnout might not be all bad.
"You never want to have a low turnout, but I think the people voting will be better informed," he said.
The senior class has revved up efforts this past week to get out the word about the vote.
"We are doing as much word-of-mouth as we can," Rouhanifard said. Announcements were sent out to senior listservs, and senior marshals are scheduled to announce the vote in their classes.
Elections board Chairman Brian Fauver said he is having seniors who could not vote last week try the revamped system and is running sample votes to ensure a smooth operation.
