Gallup said Tuesday that for the second straight night it will not conduct its daily tracking poll for the presidential race, as a result of superstorm Sandy.

The polling firm said it will assess the situation on a daily basis and provide an update Wednesday.

Frank Newport, editor in chief of the Washington-based firm, said Monday: “The ultimate effect on the overall picture of polling between now and this weekend, including election polling, will depend on what happens as a result of the storm, about which we will have a better understanding on Tuesday and Wednesday.”

On Sunday, Gallup had candidates President Obama and Mitt Romney locked at 48 percent among registered voters and Romney leading 51-46 percent among likely voters, based on a seven-day rolling average.

The daily tracking poll has become a fixture in U.S. presidential election cycles.
