Herman Cain to make endorsement

The businessman, who suspended his campaign in December amid allegations of infidelity and sexual harassment, made his pre-announcement announcement on MSNBC.
Cain told CNN earlier this week that he wasn't ready to endorse because it could "fragment" his supporters and others who are "politically homeless." Although Cain has given no clue about whom he'll support, he is close to former House speaker Newt Gingrich and was complimentary to him in GOP debates.
A GOP presidential debate will be held in Charleston, S.C., on Jan. 19, in conjunction with the Southern Republican Leadership Conference.
Mitt Romney is leading in the latest South Carolina polls, according to recent surveys compiled by RealClearPolitics.
