When George Bush became an underdog in his reelection bid, he turned for solace to British Prime Minister John Major, whose Conservative Party won a stunning upset in national elections last spring. Now, Major's Labor rivals are returning the compliment. The weekend after the election, a Labor Party delegation flew to Little Rock. Their goal: learning how Clinton strategists positioned their man to win back Reagan Democrats and applying the lessons to British politics. In another sign of a growing special relationship between the Democrats and Labor, party leader John Smith gave Clinton a rousing speech of congratulations in the House of Commons. He twitted Major for the campaign "help" his advisers gave Bush. Major sent Clinton a note, but did not speak of the U.S. elections until Smith raised the subject.
