If you really like him send him some money. Even $20 would be huge if enough people do it. We will know if he he's a chance once we see how much money he has raised.
He is my choice too. This is a very good idea and I think that a large number of ordinary folks who normally would not donate would in this election. Funding would not be an issue for an underdog candidate and it would send a HUGE message if everyone of us who complains about and dogs out the current administration would make a donation (even if only a few dollars).
