The special election between Republican Mark Sanford and Democrat Elizabeth Colbert Busch ends today in what has been an expensive and remarkably high profile race.

Public and private polling suggests the race is statistically tied going into election day and strategists in both parties believe it could be very close.

So, what do you think?  In the comments section below, we want your prediction on who wins the South Carolina special election. Make your predictions in percentages to the tenth decimal point (as in 50.4 percent) and no further, and make sure you get them in by 7 pm eastern time, which is when polls close in the Palmetto State.

Whoever comes the closest to predicting the actual result gets a signed copy of "The Gospel According to the Fix".  Second place? Two signed copies.

Get predicting!
