THEY are the polyester politicians. Wash 'em, wring 'em, dry 'em—they don't have creases. But don't get it wrong. Because sartorial elegance they have aplenty; bandgullahs dominate and there is even a well-dressed nawab in their midst. It is the political calisthenics they are having to perform which necessitates a degree of elasticity that even the redoubtable wonderfabric is finding difficult to contain. And the stretch marks are visible occasionally.
