As an outsider, the Dem party is in a funky spot politically. Whilst it economically is to the right, many of its social policies it endorses are leftist. Their emphasis on equality of outcome rather than equality of opportunity is a large part of that, regulation of expressions and policy of migration.
Where I live, most of our political parties are left of the dems economically (basic welfare is not even a debate), but many would clearly be right of them (though usually not even close to the republicans) in social policy.
