I am a huge bitcoin support and love it, but I don't think he will listen to people who are not part of his constituency (the state he represents).
It's really hard for something in its infancy to fight Big Gov. The ironic thing about this, is if they put pressure on legitimate business to NOT accept bitcoin, they actually will simply push bitcoin into the underground and it's PRIMARY use will be illegitimate services. The government isn't doing this because of "drugs". Like always, they are using common tactics to discredit something different because they are concerned about their bottom line.
I am with you brother.
