I don’t think there are any traditional liberals left in Canada. Mainly, because if there were, they would either leave the party, or be kicked out.

Concerning the USA, you might have at least one traditional Democrat, that has left the Liberals and is running as an independent.
I am thinking of Kennedy.
Though definitely not a Republican, never the less, he is disgusted with the Democrat party.
The Democrat party does not like him either.

Would he qualify as a “traditional Liberal”?
