We’re having another debate:
Participants: Still awaiting campaign responses to invitations
It is March 15. If they haven't responded by now, do you really think they will?
And an Oregon venue? Their primary isn't until May 15. Do you really think Santorum and Romney are going to abandon the campaign trail and fly off to Portland now? Either Newt will end up debating himself (and possibly Ron Paul) or Rick and Mitt are a lot dumber than I think.
