The Democratic primary for Virginia in a few days is the last big election until November. (Unlike the GOS, I don't consider the Georgia election to be significant.)

The Democratic primary pits Lieutenant Governor Ralph Northam against former Charlottesville area Rep. Tom Perriello. When the national political press have swooped in to cover the race, they’ve usually tried to map it onto the party’s broader Hillary-Bernie divide. I guess one can see why. Perriello has Bernie Sanders’ endorsement, for one thing. For another, he’s the upstart who got into the race late and appears to have created more energy around himself than the experts thought. And Northam is an establishment guy who talks about working across the aisle and has nabbed the endorsement of basically every Democrat in the state (because Perriello got in so late).

One is a Berniecrat. The other is a corporate establishment Dem.
But that's not the only difference.

Northam has spent almost twice as much money on TV ads as Perriello, his Democratic rival, in recent months — $3.7 million to $2 million, according to a source tracking media spending in Virginia.

Despite outspending Perriello two-to-one, Northam is not pulling away.
Most polls show it to be a close race, with the most recent poll shows Perriello ahead.

The poll shows that, among likely voters, 22 percent of respondents said they would vote for Perriello and 16 percent would vote for Northam.

'Internal polls' show the race to be a lot closer.
