I think Key's lack of experience and his inconsistency seriously impact his credibility. His flip-flopping is well documented but that alone's not fatal. Instead, it's his shiftiness that troubles me. It's evident in his handling of Francesca Mould's questioning over his Rail shares. If the explanation was as innocent as he claims, why not say so at the earliest possible opportunity?
Christopher Hitchens has written a devastating piece criticising McCain and Palin - particularly Palin - for lacking the essential character to lead. His piece includes this quote:
A candidate may well change his or her position on, say, universal health care or Bosnia. But he or she cannot change the fact—if it happens to be a fact—that he or she is a pathological liar, or a dimwit, or a proud ignoramus. And even in the short run, this must and will tell.Danyl at the DimPost has noted a increasingly negative tone to the campaign. His view is Labour are wrong to follow this strategy - he may be right but I think Key's character is important to his capacity to be PM.
