Most of our videos look home made. That is kinda the point of being a grass roots effort. If everything looked like it was made by a company it would seem fake and not true grass roots.
There are lots of free video editing software packages out there, and im sure what ever you make would be respected by the Ron Paul supporters.
Edit: I just listened to the song, and I often make my videos based on inspiration from songs. Check the link in my signature. Most of the good videos have great songs, but the best videos have songs that have story telling lyrics. Those lyrics are key to the message you are trying to get across and one of the things I try and avoid is lyrics that may put subliminal thoughts of negativity in the viewers head. In the song by Muse "resistance" the phrase "could be wrong" is repeated way to many times. While the over all tone of the song is love is resistance which does fit with the Rlovetion logo, it is something you should be aware of when making a video. Just my 2 cents.
