In a two party system? Sure you can. There are plenty of regressive LGBT, financial, and corporate policy supported by the DNC and you still are going to vote for them every year. For years Democrats hated LGBT groups, supported the war in Iraq, refused to raise taxes on high earners (to this day really), support bans on encryption, and have eroded privacy.

You’ve voted for them. Every. Single. Time.

And if you were one of the few who went third party, your vote had had zero effect whatsoever.
