Former Attorney General Charlie Condon will formally announce his candidacy for the Republican nomination for US Senate tomorrow in a speech at The Citadel in Charleston.

Condon is seeking the G.O.P. nomination for the seat Democrat Ernest Hollings is giving up. Condon says his announcement will come in a speech on terrorism. Condon says he thinks the most important issue facing South Carolina and the nation is fighting terrorism.

At least three other Republicans are seeking the nomination. They include Fourth District Representative Jim DeMint of Greenville, Myrtle Beach Mayor Mark McBride, and Thomas Ravenel, a Lowcountry real estate developer. Democrats seeking the seat include state Education Superintendent Inez Tenenbaum, Columbia Mayor Bob Coble and Camden native Marcus Belk.
