From the campaign:

Former Mississippi Gov. Ray Mabus and former Oklahoma Congressman Brad Carson will hold a news conference Tuesday in Charleston to make their cases for U.S. Senator Barack Obama’s candidacy.

During his tenure as governor, Mabus passed one of the most comprehensive education reform programs in America, gave teachers the largest pay raise in the nation, and was named one of the top 10 education governors in the country by Fortune magazine. In a 1999 poll commissioned by the Jackson Clarion-Ledger, Mississippians selected Mabus as the best governor of the millennium.

A Rhodes Scholar and two-term congressman, Carson won re-election to his House seat in 2002 with 75 percent of the vote. Since leaving Congress in 2005, Carson has taught at Harvard and written for The New Republic and Democracy: A Journal of Ideas, among other publications.

The event will be at 11 a.m. at the William Aiken House, 465 King St.

Here’s Obama’s new commercial in S.C. looking at education.
