I recently came across an interesting program that highlights the most popular youtube vids....for each of the candidates.
TimeTube ..type candidate's name as keyword...the larger the thumbnail, the more popular the vid.
The most popular recent Obama youtube....Tom Hanks endorses Obama....Obama music video....Obama on Ellen
Among the most popular McCain youtubes... McCain calling a college kid a "little jerk"...lol...or McCain has lost touch with reality.
Not that these measure anything.
