If one thing is different between the presidential race in 2004 and 2008, it clearly is going to be the battle on the internet. Three years ago, an online video would have had little to no impact. Today, it’s a great way to reach thousands, if not millions of potential voters.

Barack Obama’s team just sent out an email to his supporters with the embeded video below. It’s a powerful reminder of Obama’s consistent opposition to the Iraq war. More importantly, it highlights the differences between some of his Democratic rivals who originally voted for the war and are now against (Edwards and Clinton most specifically). YouTube has allowed for easier access to what cadidates have said in the past. Maybe it won’t be on the same level as television ads in ‘08, but clearly YouTube is going to play a vital role in the next election.
