MCCAIN VS. OBAMA

Florida clinched the presidency for George W. Bush in 2000, and Ohio did the same in 2004.
Quinnipiac surveyed between 1,300 and 1,500 voters in each state June 9-16. The polls had margins of error of plus or minus 2.5 percentage points for Pennsylvania and 2.6 percentage points for Ohio and Florida.

If the swing state momentum for Obama catches on all over the country, there may be a new electoral map.

The latest CNN national poll, conducted by the Opinion Research Corporation, shows Obama running strongest in the West -- and not just California.

"The 10 Rocky Mountain states have been traditionally the most Republican part of the country. So that's why it's so amazing that the polls show Obama doing well out here," said Bob Loevy, a political science professor at Colorado College.

Nevada, New Mexico and Colorado, three Western states that Bush carried by narrow margins in 2004, now look vulnerable to a Democratic takeover, even though they all border McCain's Arizona.
