Arguably, this is the way of the world. The Right is wrong and the Left gets to clean up.
That is indeed arguable.
The ubiquity of massive over-generalisations like this (if you've ever thought to yourself 'the Right just want to look after their rich cronies' or 'the left are economically illiterate' then you too are guilty) lend a lot of support to the idea that political ideologies are (partly) signalling devices, and built around evidence-resistant commitment. This is something I will perhaps develop into a more in-depth post at some point.
