Dear Mr. Obama
"Dear Mr Obama having spent 12 months in Iraq theatre I can promise you it's not a mistake."
At 1 minute 55 seconds, it's short, simple and powerful.
"When you call the Iraqi war a mistake you disrespect the service and sacrifice of everyone who has died promoting freedom... Because you do not understand or appreciate these principles Sir, I am supporting Senator John McCain for president."
The film, titled Dear Mr Obama, is the most-viewed election-related video on the YouTube website, attracting more than 11 million hits.
Made by an Iraq war returnee, it's an example of how ordinary Americans have used the website to get their voice heard.
I think I have posted this video before, but it is worth seeing again. It is powerful enough to get worldwide attention and be largely ignored by the Obama media.
