Although I wouldn't have once, I now consider myself a swinging voter. I believe strongly that in today's political climate where it seems only a highly centrist political party will ever be elected to government, it simply doesn't make sense to have strong party allegiances. Being a swinging voter allows you to support the good deeds of a government, but reprimand them when they take things too far or forget that they should be accountable.
In the end, it was fitting both that Howard should attain great political success, and that his career should end in humiliating defeat. His ability deserved the one, and his misdeeds the other.
