McCain running out of options as Obama hits 174 votes

With victories for Barack Obama in Pennsylvania and New Hampshire, John McCain was quickly running out of ways to reach the 270 electoral votes needed to win the presidency.

Mr Obama lost to Mrs Clinton in the Democratic primary election in Pennsylvania, and the state was also at the centre of his only gaffe of the campaign, when he told a San Francisco fundraiser that economic frustrations had made small-town Pennsylvania voters “bitter” and driven them to “cling to guns or religion”.
