Obama will remain in the capital on Wednesday to monitor the response to superstorm Sandy and ensure that "all federal resources continue to be provided to support ongoing state and local recovery efforts," said White House spokesman Jay Carney in a statement on Tuesday.

That means Obama has to cancel his planned appearance in campaign events in key swing state Ohio on Wednesday.

The incumbent is balancing between his job and the home stretch of his re-election campaign. Due to deteriorating weather conditions, Obama has already canceled planned campaign events for Monday and Tuesday to stay in the capital and closely monitor the impact of the potentially deadly hurricane.

Speaking after a televised statement on Monday noon, Obama told reporters that the campaign was not top priority now and he was not worried about the impact of the storm on his re-election bid.
