Only discussion and debate should settle disagreements but effort and commitment are leading traits. One person's opinion is just that an one should not assume everyone should or does feel the same way. Still if someone like trump started calling himself a democrat I'd tell him to go fuck himself and get lost. This is supposed to be the people's party and not chasers after banksters, Wall streeters, corporate lobbyist's donors. Progressives vs the DLC will have to be debated and discussed. So far the party was changing to be more progressive...every since Sander's push for income equality. The country always prospered more when there was a high corporate tax rate with a high wealth tax. Always.
