This map is so bleak. I wouldn't be shocked to see Dems lose the turnout battle in Colorado or Connecticut at this point.
Most of these competitive states in the general are having uncompetitive primaries for the Democrats. It's a total apples to oranges comparison.
Historically it's a decently accurate measure. For instance in 2018, the only states where one party won the primary turnout and the other won the General were OH, AZ, and MT. https://talkelections.org/FORUM/index.php?topic=309121.msg6582778#msg6582778
And in all 3 of those races the Republican candidate ran a bad campaign.
