McCain-Palin Bring Momentum to Fairfax

They hold their last joint campaign event Wednesday morning in the typically Democratic stronghold of Virginia before splitting up on the trail. McCain discusses national security, veterans, education, energy, earmarks and more. Palin introduces her running mate with the same fiery rhetoric she's been using all week. Again touts her opposition to the Bridge to Nowhere, which has been challenged by the media. Continues to rile up the crowd, which officials estimated at more than 23,000, with supporters interrupting at times to chant: "Sarah, Sarah!" Obama camp responds here.
