John Major has hit a fundamental fault line. Resistance to Europe runs in the British blood. A meeting called by the Referendum Party to oppose an integrated Europe was attended by over 10,000 people, far more than any crowd that attended any recent Labour or Conservative party meeting. By keeping options open on joining a single currency, Major looks like losing out twice over, with the revolt in his ranks and the ebbing Conservative support. The heart of Conservative support is anti-Europe and opposed to a single currency displacing the British pound. Tory candidates out looking for votes know that, and are going with the natural Conservative flow. Labour, on this as on other issues, has followed the Conservative line--it will keep its options on a single currency open. But on this count Labour, unlike Tory, will not lose traditional votes. If the opinion polls are right, Labour will win with a majority of about 150 to 200 seats in the 653-member House of Commons. Not many within Labour expect such a landslide. One in seven, and by some estimates one in four, votes remain undecided. And in 1992, while opinion polls had pointed to a Labour victory, the Tories came through. However, few believe the opinion polls could go as wildly wrong this time.
