WASHINGTON (CNN) - New state polls indicate that the race for the White House remains a dead heat in four crucial battleground states that could determine the outcome of the election.
CNN/Time Magazine/Opinion Research Corporation polls for Michigan, Missouri, New Hampshire and Virginia out Wednesday suggest the race between Senators Barack Obama and John McCain is statistically tied.
The survey has Illinois Senator Barack Obama up 4 points, 49 percent to 45 percent, in Michigan and ahead by 6 points, 51 percent to 45 percent, in New Hampshire. Both states voted for Democrat John Kerry in the last presidential election.
The poll has Arizona Senator McCain up 5 points in Missouri, 50 percent to 45 percent, and leading by 4 points in Virginia, 50 percent to 46 percent. President Bush kept both states in the Republican column four years ago.
Virginia hasn't voted for a Democratic presidential candidate since Lyndon Johnson took the state 44 years ago. But Obama is working hard to try and turn the red state blue: He's made numerous campaign stops there, including events Tuesday and Wednesday this week.
"The geographic patterns in Virginia are pretty much the same as in 2004, with one exception: In the area around Norfolk, Hampton Roads and Virginia Beach - a region John Kerry lost by four points - Obama appears to have a 13-point advantage. That's surprising for an area with several naval bases, and the headquarters of Pat Robertson's Christian Broadcasting Network. “Obama's getting about the same support in Northern Virginia that Kerry did four years ago,” says CNN Polling Director Keating Holland. “But that wasn't enough to turn that state blue in 2004, and it's not enough in 2008. Obama needs to do better in Northern Virginia if he hopes to carry the state."
Michigan has voted for Democratic presidential candidates in the past four elections, but it's a state that McCain hopes to turn red this time around. McCain and his running mate, Alaska Governor Sarah Palin, campaigned in the state on Friday.
“Something may be happening in Michigan,” adds Holland. “Oakland and Macomb counties, the Detroit suburbs that were the home of the Reagan Democrats, went for Bush in 2004 by a combined total of just one percentage point. But today McCain has an 18-point lead over Obama.
“So where is Obama making up the ground he is losing in the Detroit suburbs? In the southwestern part of the state, Obama currently has a 9-point edge, even though that area gave Bush a 19-point margin four years ago," he says.
While the overall political climate appears to benefit the Democrats in 2008 - thanks to an unpopular Republican president, an unpopular war in Iraq, and an ailing economy - the race for the White House remains tight, both in national polls and state polls.
"All four states are voting the same way they voted in 2004, although all are close and the Democratic ticket is doing slightly better in each,” says CNN Senior Political Analyst Bill Schneider. “It's as if very little has changed in four years. In all four states, partisans are lining up solidly with their party Independents are the key swing group. Independents are voting for Obama in New Hampshire and Michigan and for McCain in Missouri and Virginia."
The CNN Electoral Map suggests that if the presidential election were held today, Obama would win 243 electoral votes to McCain's 189, with 106 electoral votes still up for grabs (270 electoral votes are needed to win the White House). CNN's Electoral College estimate is based on several factors, including the most recent state polls, voting trends and campaign advertising spending.
The CNN/Time Magazine/Opinion Research Corporation polls were conducted Sunday through Tuesday, with 966 registered voters in Michigan, 940 registered voters in Missouri, 899 registered voters in New Hampshire, and 920 registered voters in Virginia questioned by telephone. The survey's sampling error is plus or minus 3 percentage points in Michigan, Missouri and New Hampshire and 3.5 percentage points in New Hampshire.
