Gallup has released the results of its final poll of the Presidential election finding a “statistical tie” with Republican Presidential nominee Mitt Romney at 48% and Barack Obama at 47% — with polling results now having returned to Oct 1 -7, basically wiping out Romney’s debate gains and registering high approval for Obama’s handling of Hurricane Sandy.

National polls cannot be used to estimate who will win the electorate votes. Most US states adopt the rule that "winner takes all votes" so only polls in swing states are useful.
If you look at the polls in the swing states one by one, Obama has a very clear advantage over Romney.
