Obama mocks McCain as being computer-illiterate

John McCain is mocked as an out-of-touch, out-of-date computer illiterate in a television commercial out on Friday from Barack Obama as the Democrat begins his sharpest barrage yet on McCain's long Washington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. Obama's campaign says the escalation will involve advertising and pushes made by the candidate, running mate Joe Biden and other surrogates across the country.

"Today is the first day of the rest of the campaign," Obama campaign manager David Plouffe says in a campaign strategy memo. "We will respond with speed and ferocity to John McCain's attacks and we will take the fight to him, but we will do it on the big issues that matter to the American people."
