Several of the demographic patterns are similar to what polls and primary results have shown. Obama leads Clinton among men 59 percent to 38 percent while she leads him 63 percent to 27 percent among women. Clinton leads 63 percent to 29 percent among white voters (78 percent of the sample) and Obama is ahead 89 percent to 7 percent among black voters (18 percent of the sample). However, in a difference from many of the other contests, Clinton is running about even with Obama among voters under 49 while leading him 58 percent to 37 percent among older voters.

For coverage of the battle for the vote in Pennsylvania's April 22 primary, check out the Philadelphia Inquirer's comparison of the dynamics in that state compared to Ohio (dubbed "Penn-hio" by the Inquirer) and the Pittsburgh Post Gazette's assessment of Pennsylvania as prime Clinton territory..

While we're here, not much change in the Gallup daily tracking poll. The lead has switched again from Clinton being ahead 46 percent to 45 percent yesterday, but today Obama leads 47 percent to 45 percent. But both leads were statistically insignificant given the 3 point margin of error.
