Washington: US President Barack Obama continues to lead Republican rival Mitt Romney by 4 points in the swing state of Ohio, a new poll has showed.
According to the latest CNN/ORC poll, the president draws 50 percent support to Romney's 46 percent, which remains unchanged since Oct. 9, when a CNN poll had shown Obama with 51 percent vote compared to Romney's 47 percent, Politico reports.
According to the report, Ohio is the major state, which can determine who the next president would be.
If Obama can maintain his lead there, Romney's route to 270 electoral votes is not impossible, but it's exceptionally difficult, and it adds enormous pressure on Romney to flip Wisconsin, the report said.
The presidential contenders' final lap in the race to the White House has begun, to give the US its next president by November 6.
