With six weeks to go until Election Day, just released CNN poll of polls out of Florida and Ohio, as well as a new survey out of Missouri, suggest the race for the White House just may be headed for a photo finish.
In the new CNN Florida poll of polls, comprised of four recent surveys of the state, McCain holds a razor-thin 1-point lead, 47-46 percent. The Republican presidential nominee had held a healthier margin there for most of the summer, though Obama has aggressively targeted Sunshine State voters on the airwaves by a margin of more than eight to one when it comes to ad spending. CNN considers the state a "tossup" in its electoral map breakdown.

A new CNN poll of polls in Ohio also shows McCain with a 1-point margin (47-46 percent) in that key Midwestern state, which no Republican presidential aspirant has lost and gone on to win the White House. The Ohio poll of polls, consisting of three recent surveys, also shows more than 7 percent of Ohioans still have not made up their minds. The Buckeye state is considered a tossup in the CNN electoral map.
The CNN poll of polls in Florida and Ohio do not carry sampling errors.
A new Research 2000 poll out of Missouri was also released Sunday, showing McCain with a four point lead there (49-45 percent). The perennial bellwether state that has voted for the eventual winner in all but one presidential election since 1904 chose President Bush over John Kerry by a 6-point margin in 2004 and picked Bush over Al Gore by a 4-point margin in 2000. The Research 2000 poll, which carries a sampling error of plus or minus 3.5 percentage points, also shows 6 percent remain undecided there. CNN considers Missouri as leaning toward McCain in its electoral map.
