Perhaps this is where Burnham will largely reside, the smaller scale 'sensible' policy stuff that can actually be implemented within fiscal means and isn't wildly controversial, supplemented by one or two 'big ticket' items like voting reform that won't get beat down as he will have stored up enough credit with the smaller stuff. If you take away the political extremes what most people want (I assume!) is to be able to afford to live and have the odd treat, to feel safe in their communities, access to decent quality public services and a general sense that the country is operating well for most of us.
I always feel if you stop trying to deliver ridiculous extremes i.e. virtually curbing any immigration, and focus on the day to day improvements to the economy, public services, general social and cultural prosperity, then people largely stop being concerned with much of the other policy as they are generally happy and no longer look for the silver bullet approach to solve all their problems.
