LOUIS, Missouri (CNN) - New polls in five crucial battleground states that could decide the race for the White House suggest Barack Obama is making some major gains.
CNN/Time Magazine/Opinion Research Corporation polls released Wednesday afternoon of likely voters in Florida, Minnesota, Missouri, Nevada and Virginia suggest a shift towards the Democratic presidential nominee.
In Florida, the state that decided it all in the 2000 presidential election, 51 percent of likely voters say Obama is their choice for president, with 47 percent backing Republican presidential nominee John McCain. The last CNN poll taken in Florida showed the race for the state's 27 electoral votes all tied at 48 percent apiece, among registered voters. A new CNN Poll of Polls in Florida, also out Wednesday afternoon, has Obama over McCain by 5 points. The CNN Poll of Polls is an average of the new CNN poll and other new state polls.
"The campaign season is like the hurricane season. Florida lies directly in its path. Hurricane Obama hit Florida, and Hurricane McCain. Tropical Storms Biden and Palin made landfall in the Sunshine State. The impact? Over the last two weeks, Barack Obama has been gaining support in Florida," says CNN Senior Political Analyst Bill Schneider.
Obama's also making gains over McCain in Minnesota, the state where the Republican convention was held a month ago. Fifty-four percent of those questioned are backing Obama, with 43 percent supporting McCain. That 11 point lead is much larger than the small two point advantage Obama had in the last CNN poll taken in Minnesota, one month ago.
It's a similar story in Missouri, where 49 percent of those polled are backing Obama and 48 percent supporting McCain. That's a gain for Obama, who was down five points to McCain in our last poll in Missouri, taken three weeks ago. Thursday's night's Vice Presidential debate is being held in St. Louis, Missouri. The only other new poll in Missouri, a Research 2000 survey, indicates McCain ahead by one point.
The poll also indicates Obama has a four point lead over McCain in Nevada, 51 percent to 47 percent. CNN's last survey in Nevada, taken in late August, had McCain up slightly. A new American Research Group poll in Nevada puts McCain ahead by two points.
In Virginia, a state that hasn't voted for the Democrats in a presidential contest since 1964, the new poll suggests Obama has a nine point lead, 53 percent to 44 percent. The last CNN survey in Virginia, taken in mid September, had McCain up by four points. But it's a slightly different story in American Research Group's new survey in Virginia, which indicates McCann has a three point lead.
What's behind this shift for Obama?
"Obama has gained ground among moderates in all five states," said CNN Polling Director Keating Holland. "That may have something to do with the first presidential debate. Some commentators knocked Obama for agreeing with McCain as often as he did, but moderates tend to like it when candidates appear willing to see the other side's point of view.
"In most states, Obama also won support from senior citizens and voters making more than $75,000. Those are two groups who may have been hardest-hit by the recent problems in the stock market and the financial community. Economic jitters may not last if Congress passes legislation in the next few days, but there may have been short-term gains for Obama as a result of the current economic problems," added Holland.
When factored in, the new CNN/Time Magazine/Opinion Research Corporation polls are behind a shift in the CNN Electoral College Map. CNN is moving Minnesota, and its 10 electoral votes, from toss up to lean Obama. Missouri, with 11 electoral votes up for grabs, is shifting from lean McCain to toss up. With those moves, CNN estimates that if the presidential election were held today, Obama would win states with 250 electoral votes and McCain states with 189 electoral votes, with 99 electoral votes in states still up for grabs. Two-hundred and seventy electoral votes are needed to win the White House. Obama has a 61 electoral vote advantage over McCain, up from a 40 point lead in our previous electoral map.
The poll also expanded to include three third party candidates, Independent Ralph Nader, Libertarian candidate Bob Barr and Green Party candidate Cynthia McKinney. Except for a 3 percent showing by Nader in Florida and a 4 percent showing by Nader in Nevada, no one registered more than two percent in any survey.
The CNN/Time Magazine/Opinion Research Corporation polls were conducted September 28-30, with 940 registered voters and 770 likely votes in Florida, 929 registered voters and 849 likely voters in Minnesota, 951 registered voters and 744 likely voters in Missouri, 924 registered voters and 684 likely voters in Nevada, and 925 registered voters and 684 likely voters in Virginia all questioned by telephone. The survey's sampling error is plus or minus 3.5 percentage points in Florida, Minnesota and Missouri, and 4 percentage points in Nevada and Virginia.
