In an election campaign notable for its surprises, Sarah Palin, the Republican vice- presidential candidate, may be about to spring a new one — the wedding of her pregnant teenage daughter to her ice-hockey-playing fiancé before the November 4 election.

Inside John McCain’s campaign the expectation is growing that there will be a popularity boosting pre-election wedding in Alaska between Bristol Palin, 17, and Levi Johnston, 18, her schoolmate and father of her baby. “It would be fantastic,” said a McCain insider. “You would have every TV camera there. The entire country would be watching. It would shut down the race for a week.”

There is already some urgency to the wedding as Bristol, who is six months pregnant, may not want to walk down the aisle too close to her date of delivery. She turns 18 on October 18, a respectable age for a bride — and the same age as Barack Obama’s pregnant mother when she married his Kenyan father. The Democrat has already declared Bristol’s private life off-limits as far as his campaign is concerned.
