SurveyUSA just released the first survey out of Oregon since late January. The survey shows that Barack Obama currently holds a 10% lead over Hillary Clinton. His support comes largely from males, with whom he enjoys a 62-32% advantage. He also carries every age group except the over 65 crowd. Interestingly, 70% of the respondents indicated that their mind was made up, and that group preferred Obama by a margin of 54-43%. Among those who might still change their mind, Obama led by just 44-41%.
We now have at least one recent survey in every state that is holding a primary between now and May 20th. I will publish updated delegate estimates soon, but the bottom line appears to be that if these polls up, Clinton will not be able to make any significant inroads into Obama's delegate lead over the next 6 weeks.
