John McCain is mocked as an out-of-touch, out-of-date computer illiterate in a television commercial out Friday from Barack Obama as the Democrat begins his sharpest barrage yet on McCain's long Washington career.

The new fighting spirit comes as McCain has been gaining in the polls and some Democrats have been expressing concern the Obama campaign has not been aggressive enough.

"Our economy wouldn't survive without the Internet, and cyber-security continues to represent one our most serious national security threats," [Obama spokesman Dan] Pfeiffer said. "It's extraordinary that someone who wants to be our president and our commander in chief doesn't know how to send an e-mail."

McCain gets emotional at the mention of military families needing food stamps or veterans lacking health care. The outrage comes from inside: McCain's severe war injuries prevent him from combing his hair, typing on a keyboard, or tying his shoes. Friends marvel at McCain's encyclopedic knowledge of sports. He's an avid fan - Ted Williams is his hero - but he can't raise his arm above his shoulder to throw a baseball.

"Six months ago, no one would have pegged McCain as the most cybersavvy of this year's crop of candidates. At 63, he is the oldest of the bunch and because of his war injuries, he is limited in his ability to wield a keyboard."

In certain ways, McCain was a natural Web candidate. Chairman of the Senate Telecommunications Subcommittee and regarded as the U.S. Senate's savviest technologist, McCain is an inveterate devotee of email. His nightly ritual is to read his email together with his wife, Cindy. The injuries he incurred as a Vietnam POW make it painful for McCain to type. Instead, he dictates responses that his wife types on a laptop. "She's a whiz on the keyboard, and I'm so laborious," McCain admits.
