MPs have had a torrid time in recent weeks.
Climate change policy can create endangered species, as Kevin Rudd found out.
Governments worldwide have grappled with various responses to greenhouse gas emissions and Australia's version of an emissions trading scheme (ETS) wasn't much different to ours.
When politicians throw mud, does some of it stick? Or is it counter-productive and do voters treat it with contempt?
From the evidence of past mud-slinging, it doesn't pay and it usually ends up all over the throwers.
Post-budget best case scenario for the Government: Most people react responsibly, saving or investing their tax cuts. Inflation rises but far less than Treasury's forecast.
Surprising misconceptions and startling contradictions surround the Government's affirmation of the United Nations Declaration on the Rights of Indigenous Peoples.
When Rodney Hide complained last year that the Government "wasn't doing anything" the point he was trying to make was that it hadn't set a course for the sort of economic reform it had talked about before the election.
During its first year in office, the Government managed to run its agenda without suffering any noticeable damage. When difficulties did arise, Prime Minister John Key found remedies and shrugged them off in that way he has of making problems appear insignificant.
On Tuesday in Parliament John Key will make the most important speech of his political career.

This year is the Government's second since taking office, and its actions over the next 12 months will influence the outcome of the 2011 election.
What is it with small parties? On an MP for MP basis they get into a hugely disproportionate amount of trouble.
Look at the figures. National 58 seats, Labour 43, ACT five and the Maori Party five.
If the impact of the international recession on New Zealand's economy was more severe now than a year ago, or even if it was the same, the Government would have a problem.
It isn't, and in terms of public perception the Government clearly doesn't have a problem.
Few things annoy MPs more than the media poking its nose into their expenses, and there are few issues with so many grey areas to poke into.
Electoral law is on Parliament's agenda and the search for consensus on legislation to replace the Electoral Finance Act has started.
The Act, arguably the last government's worst blunder, was repealed in one of the first bills passed after National won last year's election.
Well, so much for a grand coalition on the emissions trading scheme.
Grand shambles, more like, although there's more to this than meets the eye.
