“I would think forcing them to remain in a hostile state would be a good thing. Someone explain why we should get them to move.”
Logistics alone will preclude them moving it. You cant reschedule a large convention this late. SO .... having a petition boom-let is a win/win ... the DNC will *have* to hold the convention in a state that Democrats are calling names!
The American Historical Association had planned to hold their 1994 annual convention in Cincinnati, but because of that vote, to show their displeasure, they voted (at their 1993 meeting in San Francisco) to move their next convention elsewhere, even though that cost them something like $500,000 to do so. It is, like other professional academic organizations, an organization very friendly to leftist, feminist, and pro-gay types.
Of course the cost would be exponentially higher to move a national political convention, and impossible on short notice.
