I'll be honest here, Obama is the only one of these people I am familiar with. ![Tongue](https://talkelections.org/FORUM/Smileys/classic/tongue.gif)
Brison is a Liberal MP in Canada. Was a Progressive Conservative MP from 1997-2003. Carrió is the leader and founder of Civic Coalition ARI, a centrist political party aligned with Argentina's President Mauricio Macri and his Cambiemos alliance.
Piñera is the conservative/National Renewal President of Chile. Bernier is a conservative MP from Canada who is libertarian-ish and ran for leadership in 2017.
You'd prob support Brison-Carrió. Maybe Obama.
