You can't bet on whether George W. Bush or John Kerry will win the 2004 presidential election in a Las Vegas sports book, which accepts bets on designated sporting events only. Nor can you make the bet in a Las Vegas race book (though it could be argued that the presidential election is something of a horse race). However, there's currently a brisk market being made by several offshore Web-based sports books. At this time, George Bush is about a 6-5 favorite.
