I'd say you're the one who has missed the point, which is that McCain is looking for any explanation for his loss that doesn't include the fact the he ran a lousy campaign. And I'd bet his staff made use of modern communications, whether McCain was aware of it or not.
Obama had had the fundraising advantage throughout the campaign, yet he was behind when the financial crisis broke. McCain defeated himself with his hapless and confused behavior during that crisis, and the fact that he delivered mediocre to poor debate performances. The money advantage did not win the campaign for Obama, but McCain's poor performance during the final weeks and during the three debates, and that was the period when the most important exposure to the voters was free.
And Howard Dean, not Obama, was the first to make very effective us of the internet for fundraising.
Modern communications? Yep, McCain's camp I'm sure had cellphones, and laptops and internet connectivity. That's not what we're talking about. And, the fact that you don't understand the impact of technology as an enabler, or the breakthroughs and pioneering technologies developed and employed either by or for his campaign, says you don't understand the issue any better than the Republican National Committee.
