One of the narratives being pushed for months is that Sanders voters won't vote for Clinton in the general election. Is this true? I have no idea. Is this true? Nobody has any idea. A few randos on the internet are not data. I thought the PUMAs were funny in 2008 but I didn't think they were actually a nationwide movement. But the broader point of this narrative is that Sanders voters are somehow illegitimate. They are not loyal Democrats. They don't matter.
The important thing is that the responsibility to win elections is on the candidate, not the voters. It's the candidate's job - with the help of hundreds of millions of campaign funds - to get them to the polls and to pull the lever for them. Making excuses for a loss many many months out is really weird. Blaming the voters - which Democrats love to do - is gross. Stop it. Also, too, midterm elections. Every time I say "this is an election about nothing" and then they blame the voters for not showing up. Show up for what?
