DES MOINES, Iowa (AP) - The race in the Iowa caucuses between Mitt Romney and Rick Santorum remains too close to call.
Not all precincts have reported in and election officials do not know precisely when all the votes will be tabulated.
The Associated Press is continuing to update vote totals as the remaining precincts report in, but with the vote so close, the AP isn't calling a winner until the vote total will no longer be subject to adjustment or correction.
