Barack Obama and Mitt Romney are deadlocked in four national polls as the 2012 race for the White House enters a dramatic final 48 hours.
ABC/Washington Post, Rasmussen, George Washington University/Politico, and Fox News polls all found the race as tied. NBC/Wall Street Journal gave Obama a one-point advantage.
Obama maintains a polling edge in all-important Ohio with a 2.8 per cent lead in the RealClearPolitics average. Romney leads by 1.4 per cent and 0.3 per cent in Florida and Virginia respectively – two swing states he must win if he is to oust Obama.
