A pox on both your houses

With yesterday's ReachTEL poll, we have recent attitudinal polling from the three houses that regularly do this kind of thing.

In a manner similar to the way in which we use a latent Dirichlet process to estimate the primary vote for each of the major parties, we can use a latent Dirichlet process to estimate the degree of happiness or unhappiness with the Prime Minister and the Leader of the Opposition.

If I could beg your indulgence with the traffic light metaphor for chart colours, the results follow:

Update

We can also plot the results for the Prime Minister (PM) and Opposition Leader (OL) side-by-side.
