The Nevada election results—and thus the results in the Harry Reid-Sharron Angle race—may be delayed, so says a statement on the Nevada secretary of state's website:
There may be a delay in reporting early returns in all statewide Nevada races due to a power outage at a Clark County polling location. All voters in line at that site as of 7 PM will be allowed to cast their votes. No results of any statewide races can be reported in any county until all polls across the state are closed. There is no estimate at this time of how long any delay might be. We’ll keep you posted.
