[+/-] Latest poll of battleground states shows Kerry in significant lead

The latest Zogby Interactive poll of battleground states, taken over five days immediately after the Edwards announcement, gives Mr. Kerry his best showing since Zogby began conducting twice-a-month polls of 16 closely contested battleground states. The bottom line: if the vote were held today, Kerry would beat Bush 322 electoral votes to 205.

Notably, all three of the states in which Bush leads are well within the poll's margin of error, while Kerry's lead is in the clear in half of the twelve states he leads.
