Who's Likely to Win Nevada? Roll the Dice

— -- In a state that is perhaps best known for gambling and the unique allure of its famous 'Sin City', the presidential election odds are tight, with polls showing a dead heat between Sen. Barack Obama and John McCain.

The state went Democratic in 1994 and 1996, but voted Republican in 2000 and 2004.

During the frenzy of the primaries, Nevada's caucus went for Hillary Clinton over Sen. Barack Obama but Obama walked away with more delegates in the process.

McCain, meanwhile, came in third in the GOP primary behind Mitt Romney and Ron Paul.

As this red-and-blue roulette wheel begins to slow its spin, it is still unclear where the ball will drop come November.
