Scotland's pro-independence leader is insisting his campaign is headed for victory — one month before the historic Sept. 18 referendum.

First Minister Alex Salmond told The Associated Press on Monday that those seeking independence have always been the underdogs.

But Salmond seemed buoyant after new polls suggest that Scotland's voters are only narrowly divided on whether to leave the United Kingdom. However, polls consistently show those favoring union in the lead.

He said the day after the vote Scots won't "wake up and find there are three taps in every house - whisky, oil and water." But he added that independence activists can build a more prosperous and just society.

Salmond has come under fire for economic arguments, particularly the question of which currency an independent Scotland would use.
