Electoral Vote Trend Visualization Take Two

Because it would be bad luck to leave the old one with McCain ahead, here is my new electoral graphicalization. NeoOffice(2.2.2) works on this MacBook but looked bad. Excel came through again. I got the single center gridline at 50% to come out somehow (Excel stopped rejecting that modification) and I stuck a picture behind it. Time order is geological as before. I made it A3 size (click on it!) but some inexplicable artifact came into the horizontal bars. Maybe it is "shadow" and I'd have to go back through the "wizard". As before, data is from electoral-vote.com and inspiration from EVStrength.com.
