Bernie Sanders ticket

I am looking for a ticket to see Bernie Sanders at Tivoli on October 11th. I absolutely love him and was so sad to only now see that he is coming here, and that it was too late to get a ticket.

If anyone has an extra one I would LOVE to have it.

If anyone has recommendations on other places to look I would also really appreciate it. Ticketswap doesn't appear to have an event listed for this?
