A Geographic Analysis of PA, OH and VA General Election Polling

(Cross-posted on MyDD and Daily Kos)

A number of state polls have come out in recent days for Pennsylvania, Ohio, and Virginia.  The numbers overall look good for Barack Obama, with him leading John McCain in Pennsylvania in all four polls released in May; Obama leading outside the margin of error in one poll in Ohio while being within the margin in two others; and a very competitive race in Virginia as well, with one poll there showing Obama up by seven points (links to polls used are provided at bottom of this diary).  What I wanted to do in this diary is to look at the regional breakdown in Pennsylvania, Ohio, and Virginia to examine Obama’s geographic areas of strength and weakness.
