Sen. John Kerry's strong performance in the first debate has helped him among likely voters in 16 battleground states, according to the latest Zogby Interactive poll. Kerry "now holds leads, albeit some of them razor-thin, in 13 states, an improvement from the 11 he held three weeks ago."
"Notably, Mr. Kerry overtook President Bush in Ohio, a critical swing state where he had been trailing since mid-July."
Update: The new AP Poll shows Kerry with a four-point lead among likely voters, 50% to 46%. But a new Marist College poll shows Bush with a three-point lead among likely voters, 49% to 46%.
Here are some notable state polls:
