Presidential elections - It’s time for candidates to be specific

THE list of Republicans hoping to unseat president Barack Obama next year grew longer yesterday when former senator Rick Santorum announced his intention to elbow his way into an increasingly crowded field of Pennsylvania Avenue aspirants.

Already former Massachusetts governor Mitt Romney, former house speaker Newt Gingrich, former Minnesota governor Tim Pawlenty, US representative Ron Paul, and former Utah governor Jon Huntsman, a former American ambassador to China, have declared their candidacy. Texas governor Rick Perry and congresswoman Michele Bachmann have expressed an interest but have not made a firm declaration.

And then there’s Sarah.
