Look, it would be nice if all politicians always stuck to their guns when right and always changed their mind when they were wrong (as subjective as 'right' or 'wrong' are). The reality is that politicians are not like that. You have the principled ones, and the compromisers.
Personally? I'll take a politician who always stands up for what he believes in over one who bends with the wind any day. They will always make some crappy decisions along the way, but they will make some tough ones too - and the tough decisions are the ones that benefit people in the long run. Plus, you know what you are going to get when you vote for them because they follow through.I think Gough Whitlam was a horrible, horrible PM but he stuck to his guns and implemented reforms he believed in and was elected for. Even though Whitlam was IMO wrong a lot more frequently than Rudd, Whitlam also achieved a lot more than Rudd did through strength of his convictions.
And at the end of the day, a strong government is needed to push through real reforms. Any government can come in afterwards and fix the bad decisions. Look at WorkChoices.
Good post. The bolded bit pretty much is what I was trying to get at. Doesnt matter which party they belong too!
