I am, actually, a beautiful and unique snowflake seeking a candidate to vote for who reflects my own hopes, dreams, and values and is worthy of my blessing. Whether you think I’m being reasonable or not is irrelevant, this is what I believe, and if the democrats want the votes of me and people like me, then they better start acting in a way that convinces me they deserve my blessing.

If everyone voted for them they would have a mandate to move further left.

They have precisely zero interest in moving left regardless of how much power they’re given.
