Along with its poll on the Oregon Senate race, Survey USA has also now released its finding in the Democratic presidential contest in Oregon. Not surprisingly, Barack Obama leads Hillary Clinton, 52 percent to 42 percent.

I say not surprisingly, because other polls showing test matchups against Republican John McCain also had put Obama ahead of Clinton in Oregon. Plus, it fits with what both campaigns have been telling me about the status of the race here, and they have the most extensive polling of all.

Also not surprisingly, there is a big gender split, with Clinton doing better among women and Obama doing better among men. And younger voters are more likely to side with Obama.

Voters who say they are primarily concerned about the economy are almost equally split between the two. But those who say their top concern is the war in Iraq lean heavily toward Obama.

Overall, the race is close enough so there is an incentive for both sides to campaign hard here - and that's exactly what seems to be happening.
