In terms of accuracy, from a statistical standpoint, if we were to stop voting right now and only count the votes that had been cast, statistically speaking, I can pretty much guarantee you that Amendment One passes," Teitleman said. "Now obviously, as more time goes on, more votes get cast, and there's also the potential for shifts."

Teitleman said he thinks "the vast majority of voters don't fully understand the ballot measure."

"They're voting on a gay marriage ban only, not a civil union ban, which is actually what the amendment is about," he said.
