SC has 25 GOP, 14 Democratic House primary races

COLUMBIA, S.C. (AP) - South Carolina Republicans have nine incumbents giving up seats among 25 contests that will play out in the upcoming primary.

Meanwhile, two Democrats are giving up their seats among the 14 primaries for the minority party in the lower chamber.

All 124 House seats are up for election in November. The Senate's 46 members don't face voters until 2012.

Republicans control the House with 73 seats to 51 for the Democrats.

Observers don't expect many incumbents to lose re-election bids in Tuesday's primary.

Legislators elected this year will decide how new political maps are drawn. That includes deciding how to draw a seventh U.S. House seat many expect the state will gain from population growth in the 2010 census.
