Yeah the rest of the party does not like him much, and CONAEI (which is the indigenous movement as a whole) itself also does not. However, a lot of indigenous will vote for him most likely because of how pissed (rightfully too) the indigenous communities are at Arauz and Perez is for all his right wing pro US talk still saying he will throw the IMF out of the country and cease extraction operations in the interior. Correa supporters have really long term fucked their relations with indigenous living inland with their extraction policies and it's likely the conflicts with CONAEI will continue to escalate regardless of who wins the election.
