From National Review Online:
I hear from David Johnson of Strategic Vision that his company will be releasing a Pennsylvania poll tomorrow .
The poll, conducted April 4-6, 2008 of 1200 likely Pennsylvania voters, shows Clinton leading with 47 percent to Obama 42 percent. Interestingly, in the general election match-up it shows Clinton 45 percent to 42 percent for McCain; and McCain 48 percent to 41 percent for Obama. For the Democratic primary the margin of error is +/- 4.5% for the general election it is +/-3%.
The SurveyUSA numbers Rich posted in the Corner are fascinating, but so far, other pollsters aren't seeing the Hillary bounce that SUSA sees...
UPDATE I: Obama's unprecedented ad buy ($2.2 million per week).
UPDATE II: Potential explanations for the disparity between Quinnipiac/Rasmussen/Strategic Vision and SUSA can be found here and here. Perhaps Poblano can dissect these numbers for us soon on his thoroughly insightful blog (FiveThirtyEight.com).
