Canadian Prime Minister Paul Martin (L) and his wife Sheila look at his glass of white wine during their tour of the Featherstone Estate Winery and Vineyard in Vineland, Ontario, June 18, 2004. Paul Martin could stay prime minister even if his ruling Liberals end up with fewer seats than the opposition Conservatives in the June 28 election, because the Canadian political system favors the incumbent.
