Why did it take Romney a long time to concede?

Quote:


"Arriving at his suite in the Westin Boston Waterfront ­hotel, Romney received regular updates from his staff. He made small talk about the Patriots and the Celtics and played with his grandchildren. He was about to concede around 11:15 p.m when Republican strategist Karl Rove made his now-infamous appearance on Fox News Channel, insisting that his own network was wrong in calling Ohio for the president."

"The concession call was canceled, followed by an hour of uncertainty. Then, after Fox ­executives dismissed Rove's concerns and stood by the network's projection, Romney said: Call the president."
