British Labour Party: continued pink-neoliberal policy from 1997 through to 2015, with a shade more pink from 2010. It went down from 43% of the poll in 1997 to 29% in 2010, and recovered only to 30.5% in 2015.
2017: left policy. Share of poll up to 40%, and overall turnout up to 69% (which still leaves much work to do, but...). 3.5 million extra votes gained.
French Socialist Party: continued pink-neoliberal policy. 2012: won the presidency and a parliamentary majority (with small allied parties).
