Here are today's numbers:

Today's other polls look like this:

• Battleground tracker (.pdf): Obama 51/McCain 43 among likely voters
• Los Angeles Times/Bloomberg: Obama 50/McCain 41 among likely voters
• CBS News/New York Times (.pdf): Obama 53/McCain 39 among likely voters
• Pew: Obama 49/McCain 42 among likely voters
• Ipsos-McClatchy: Obama 48/McCain 39 among registered voters

Looking across all of these surveys, Obama polls at or near 50 percent (48 percent to 53 percent) and McCain performs at or near the low-40s (38 percent to 46 percent). There will likely be one more round of polling today reaching voters who have not yet viewed the debate, but the numbers above give a fairly good baseline to where the race stands heading into the debate -- a solid national advantage for Obama that McCain will have to whittle away at quickly if he has any hopes of winning the presidency.
