Another race, in South Carolina, also is being held Tuesday. Voters in the
Palmetto State's 5th Congressional District are going to the polls to
determine who will succeed Mick Mulvaney - now the White House budget
director -- in Congress. Millionaire developer Ralph Norman, the Republican,
is favored over former Goldman Sachs tax adviser Archie Parnell, the
Democrat.

Georgia's race, by contrast, is locked up in the polls - and Democrats see
it as a critical pickup opportunity after having lost two earlier special
elections in Kansas and Montana. Democrats are eager to advance the
narrative of voters delivering a referendum on President Trump's policies
but have yet to snag a House victory to support it.
