Candidates Tout Different Routes To 'Energy Security'

Originally published on Fri October 5, 2012 11:07 pm

He reiterated that goal in the opening minutes of the presidential candidates' debate in Denver this week.

Barack Obama made history in Virginia four years ago when, on his way to winning the White House, he became the first Democratic presidential candidate to capture the state in more than four decades.

His surprisingly comfortable 53-46 percent win over Republican John McCain mirrored more closely than any other state the 2008 national result and provided potent evidence of demographic and economic changes that have been sweeping the Old Dominion.

It's more diverse, wealthier, better educated than ever before.

A lawsuit against the University of Tennessee and its athletic director has revealed that earlier this year legendary women's basketball coach Pat Summitt felt that the school official was trying to force her to step down from her job.

That stands in contrast to statements Summitt made last spring. The coach, who is dealing with early-onset dementia, said then that it was her decision to become "head coach emeritus."

Summitt also says in an affidavit, however, that her feelings might have been due to a misunderstanding.
