Not really.
It proves that Mark Warner is well-liked, although it’s not clear whether his support is all that deep. Given how well-known Gilmore is and how strongly he’s run in past races, one would expect him to poll stronger. By contrast, Tom Davis isn’t well-known outside his Congressional district.
Also, it’s not a given that Mark Warner will run. State Democrats want him to return to the Governorship.
So, who should the GOP nominee be? Jim Gilmore if Mark Warner does not run, Tom Davis if Warner does run.
Davis if we want to commit complete seppaku in this race. Then we’ll be giving VA the NJ treatment. We keep lowering the bar, and the rodents will be waltzing into contests unthinkable just a few years ago.
You’re right that Tom Davis, who is running behind Gilmore in this poll, is not as well known statewide as Gilmore. Once the conservative voters outside Tom Davis’s Northern VA bailiwick learn what kind of “Republican” Davis is (the liberal kind), he’ll do even worse.
