Read back that list of coalition disagreements and it reminds you that they were issues on the margins of most voters' concerns whereas there is a surprising degree of cross party agreement on macro-economic policy, welfare cuts and schools reform letalone the proposals the two men will highlight today - be it childcare subsidies, pension reform or road tolls.
For if Romney is that adamantly opposed to Medicare cuts, without qualification, on what basis will he ever be able, letalone willing, to advocate Medicare reform of his own?
