McCain camp mood

From NBC's Kelly O'Donnell
Senior staffers are gathering to spend time with Sen. McCain at the "family villa" they are using tonight on the hotel grounds.

Various senior staffers describe McCain's mood as "good" and "he's fine."

There is a collective sense among staffers that this has been a "valiant effort" and a "great fight" in "historically difficult times."

Other describe a feeling of "no regrets" and members of the senior team contend they "left it all on the table."

One advisor says McCain himself feels "that he let his staff and supporters down."

They continue to watch results and await more actual vote totals.

No details yet on when Sen. McCain will appear.
