Remove partisanship and allow the senate to function without influence of political party affiliations. More than ever, we need the senate to be a sober thought.
Elect and the government of the day should not be able to appoint only those people who follow its party line. If the senate is to function properly, it should be non-partisan.
Either abolish or dramatically change its mandate, composition, and selection process so as to not simply be a reflection of the governing party of the day.
