Scott Walker is set to announce his presidential campaign on July 13, and recently released a new ad on his YouTube channel.
We watched the Conservative Crusader's video and couldn't help but notice that the imagery and soundtrack felt familiar. Almost as if it belonged in Gotham City.
So we took the audio from the trailer for The Dark Knight, and played it over the ad. We made only one edit, cutting out the middle 25 seconds from the Batman trailer, so that both the trailer's audio and the Walker video would end at the same time.
