President Barack Obama and Republican challenger Mitt Romney are in a dead heat ahead of Election Day on November sixth.

Nationwide polls indicate an exceptionally closer race, but it's believed Obama will secure 20 to 30 more electoral college votes. More and more forecasts are predicting the incumbent's win.

Also, more Democrats are known to have taken part in early voting by some 28 million Americans.

The Obama camp is expecting a sure victory.

Meanwhile, in the key battleground state of Florida, the Democratic Party has filed a lawsuit requesting an extension of early voting since there are not enough polling locations.
