(CNN) - John McCain does not appear to be making up ground in Ohio, the key battleground state that is crucial to keeping his White House hopes alive.
According to CNN's latest poll of polls of the state, the Arizona senator now trails Obama by 6 points there, 50 percent to 44 percent. That gap is two points wider than it was Monday and double what it was one week ago.

No Republican has won the presidency without carrying Ohio, and barring a major upset in another big state, the state's 20 electoral votes are a must win for McCain. The Republican presidential candidate is expected to spend two full days there later this week.
The latest Ohio poll of polls consists of recent surveys from LA Times/Bloomberg (October 25-27), Reuters/Zogby (October 23-26), and CNN/Time/ORC (October 19-21). CNN Poll of Polls do not have a margin of error.
Meanwhile, a new poll of polls in Florida shows a similar story. The Arizona senator trails Obama by 4 points there, 49 percent to 45 percent. That gap is 3 points higher than it was earlier today and is largely due to a newly released survey from LA Times/Bloomberg showing McCain down 7 points in the state. The Florida poll of polls also includes surveys from Suffolk University and Reuters/Zogby.
