Ante-post betting

Sir: Genial Jo Grimond's advice to 'not bother reading the opinion polls before 6 June' is like telling the punter at the track to close his eyes until the last furlong. He's right, if all polls provided were a prediction of the outcome. For that, read 9 June (a.m.).

But polls, properly reported, can provide much more. They record the progress of the campaign, public reactions to politicians' promises, a guide to what issues are cat- ching the public interest and which political stars are waxing (and waning) but, most usefully, they can provide a rich body of in- formation and analysis of reaction of men/women, young/older, class, region, trade unionists, etc, as the campaign pro- gresses for those who are interested. If you're not, ignore 'em.

There aren't as many undecideds (many of whom won't vote anyway) as some would have you believe.
