Political campaigns are all about seducing audiences. So why shouldn’t someone like me be out here, reviewing the art — or artlessness — of the seduction? Presidential contenders do not win merely by trumpeting their achievements and policies. No, their instrument has to resound with some other, ineffable qualities. Although the laws of attraction vary from voter to voter, it seems that we look in the early days of a presidential race for connections, in some of the same ways casting directors use their antennae to winnow down auditioning actors. We want someone who feels right for the part.
