FAIRFAX, Va. — Mitt Romney struck a valedictory note Monday as he rallied supporters at back-to-back events in the crucial state of Virginia — but with two more election-eve rallies to go, in addition to two newly added Election Day events in Ohio and Pennsylvania, the GOP presidential nominee still had miles to go before his 17-month campaign journey ends.

Appearing onstage with his wife, Ann, and speaking before an audience of 8,500 people inside George Mason University's Patriot Center here, Romney told supporters that "your voices and your energy and your passion are being heard all over the nation."

"If anyone wants to know where the energy is, if anyone out there that's following American politics wants to know where the energy is, just come right here in this room and you'll see it," he said to a roar from the crowd.
