Are politicians placing too much emphasis on tech?

This story in USA Today got me thinking. Are politicians placing too much emphasis on the Internet and other digital technologies? There's no question that the Internet can help politicians reach the grassroots (and raise money), but could it be they're actually outracing the public in this regard? Consider:

John Edwards delivers campaign messages via Twitter, which is suddenly popular but hardly mainstream. Senator Clinton has a chief technology officer. A candidate for governor of Kentucky, Billy Harper, uploads campaign speech videos from his Wi-Fi enabled bus. Politicians are talking about pushing videos and text messages to smart phone users.

Rudy Guliani's JoinRudy2008 offers up an embeddable widget so other sites can help collect e-mail addresses and other information. Mitt Romney looks for donors using software from Salesforce.

Is this really where the electorate is? Or have candidates let a bunch of over-enthusiastic tech wizards and journalists push them too far? Is the tech strategy a risk in any way? Does it disconnect politicans from average folks?
