I think some members of the general public could get in, but only after the invited guests. You might consider calling the venue now to ask, so that if the public can get in, you can make plans accordingly. (Then you can give the rest of us FReepers who live in other states a post-debate report.)
My tagline until the election:
A vote for Kerry-Edwards is a vote for Osama bin Laden, Saddam Hussein, Jacques Chirac, the UN, International Criminal Court, and Hollyweirdos.
Failure to vote, or a vote for a minority party, is a vote for Kerry-Edwards (unless you’re a liberal/Leftist who’ll vote Nader, a minority party, or stay home).
