** US Presidential Race Back at Full Speed After Superstorm **
U.S. President Barack Obama has told supporters in the "battleground state" of Colorado that Americans unify during times of crisis, referencing the onslaught of Hurricane Sandy earlier this week and a mass shooting that took place in Colorado earlier this year.
Having resumed campaigning after several days off to deal with storm recovery, Mr. Obama said Thursday in Boulder that America rises or falls as "one nation, one people."
He also said he is not afraid to make unpopular choices, such as the government bailout for the auto industry during the early months of his presidency.
Mr. Obama's Republican rival, former Massachusetts governor Mitt Romney, campained in Virginia Thursday, another crucial state in the November 6 election.
Mr. Romney told supporters in Roanoke that middle income Americans have been "squeezed" financially during Mr. Obama's first term in office. He says incomes have dropped while necessities such as gasoline and health insurance have gone up.
Thursday, New York City Mayor Michael Bloomberg endorsed Mr. Obama for a second term. The mayor, a former Republican turned Independent, cited the president's efforts to fight pollution from cars and factories. Many scientists say carbon emissions contribute to global warming and possibly more powerful storms like Sandy.
**Hurricane Death Toll Rising, NYC Marathon Still On**
The U.S. death toll from the powerful storm that ravaged the East Coast is above 90 and rising, as emergency workers canvass flood- and fire-ravaged neighborhoods, but New York City Mayor Michael Bloomberg says the city will carry on Sunday with its annual, world-famous marathon.
Police say at least 59 people were killed as Sandy pummeled New York City and New Jersey.
But Mayor Bloomberg vowed that Sunday's event will go on as scheduled. He said the event should not overtax the police department because it is on a Sunday, when there is less street traffic. Canceling could also put more strain on already-strapped business owners, as the prestigious event draws thousands of runners and spectators, and millions of dollars, to the city.
Power is still out in much of lower Manhattan and surrounding boroughs. The local electricity company says it will be several more days before the grid is fully up and running again.
Subways and buses resumed limited service Thursday after a four-day shutdown.
Emergency workers are pumping out flooded tunnels and buildings as the city and its suburbs struggle to recover. To avoid traffic gridlock, cars with fewer than three people inside are not allowed into the city.
Schools remain closed, and hundreds of thousands still have no electricity -- a major hardship in a city where many live in high-rise apartment buildings with electric elevators.
New York authorities are warning people against swimming or boating in the city's rivers and bays to avoid polluted water.
