Washington: Presumptive Republican nominee Mitt Romney leads President Barack Obama by two points in the first national daily tracking poll in run up to November presidential elections.

While Romney is supported by 47 percent of national registered voters, Obama has backing 45 percent in the inaugural Gallup Daily tracking results from April 11-15. However, this comes within the three percent margin of error.

Notably, 65-year-old Romney is yet to be formally declared the Republican presidential nominee.

Gallup said this initial report is based on interviews with 2,265 registered voters, and highlights the potential closeness of this year's race, with Romney and Obama essentially in a statistical tie.

Gallup's previous general election trial heat, from a national poll conducted March 25-26, showed Obama with a slight 49 percent to 45 percent lead over Romney.

However, according to the Real Clear Politics average of polls, Obama leads Romney by three percent nationally, although the average doesn’t take into account the latest Gallup numbers.
