A vote is a vote.
An "enthusiastic" vote doesn't count any more than one cast by a voter holding his or her nose.
So, your candidate didn't make it past the primary; so, the Democrat on your ballot is, in your opinion, "too liberal", "too conservative" or "morally flawed"; so, the Republican yard signs and bumperstickers in your area outnumber ours 10 to 1; VOTE IN NOVEMBER AND VOTE FOR EVERY DEMOCRAT ON YOUR BALLOT!
With exceptions too few to even mention, any Democrat we can elect will make YOUR life better---more just, more humane, more tolerant---than any Republican.
And, yes, I know all about the GOP efforts in many states to overrule election results they don't like. But, you know what? If we don't GOTV, they won't even have to decide if they are REALLY willing to silence the voices of their constituents and they won't have to defend their fascist bullshit in the courts. We will have conceded the game before they even had to suit up and take the field.
Democrats---young, old, rich, poor, urban, rural, no matter what creed or color and no matter who they love---VOTE!
I AM A DEMOCRAT!
