But do people generally vote for parties based on their attitude towards the budget/austerity plans? Because my experience is that the big parties in most countries cover so many topics in their political agendas that people are voting for them for all manner of different reasons. Sometimes it's the social/moral aspect that they care about more than the economic one, and sometimes vice versa. It's unlikely any conservative will vote for the more left leaning party based on a dislike for austerity, and vice versa.
