The one that currently doesn't have a centre-right government.
I'm not necessarily talking about their current government, but the state of their government/nation.
For example, a country that currently has a rightwing leader that also still has
-single-payer healthcare
-free college
-gay marriage
-nondiscrimination laws
-mandatory paid leave
-quality social security after retirement
-universal childcare and pre-school
-progressive taxation
-strict separation of church and state
-high minimum wage
-high corporate regulation
-decriminalized marijuana
-fair criminal justice system
-high quality labor & consumer protection & environmental laws
-high quality voting/electoral system
-internet neutrality
-massive investments in infrastructure/education/training/science/clean energy
-more diplomatic and dovish foreign policy
-ethical campaign financing
-equal pay for women
-youth jobs programs
-support for afterschool and summer learning programs
-strict gun regulations
-high quality treatment of any native populations
etc.
should rank much higher than a country with none of those things but currently has a leftwing leader.
