Now it's Barack Obama's turn.

Following a stop last Thursday by Democratic presidential candidate Hillary Clinton for a few hours at the Sioux Falls airport for a rally, rival and front-runner Obama will make his first visit of the campaign to South Dakota, the state party said this afternoon.

Party legislative director Matt McLarty confirmed Obama will come to the state Friday, but no other details were immediately known.

Clinton's husband, former President Bill Clinton, campaigned for her on Saturday in Rapid City.

The South Dakota primary is June 3.
