On the final day of campaigning over Scotland’s future, both sides made emotional appeals to wavering voters to come to their side. Former Labour Prime Minister Gordon Brown’s voice cracked as he exhorted voters to stay in the U.K. and emphasized the finality of tomorrow’s vote. Five polls in the past 24 hours showed the anti-independence Better Together group backed by Prime Minister David Cameron and the main U.K. parties leading the “yes” campaign — four of them by 52 percent to 48 percent, excluding undecided voters.
