With South Carolina's GOP presidential primary a week from Saturday, TV viewers in the state are getting an eyeful of political ads. It seems almost everyone who is running has bought time. And so have the superPACs, which are forbidden to coordinate with the campaigns.

We've been through this with him before, so talk from Comedy Central's Stephen Colbert about running for president needs to be viewed with suspicion. He's at it again and promises a "major announcement" on his show tonight.

Texas Gov. Rick Perry announced his presidential campaign in South Carolina last August, but it may soon come to an end in the same state where it started. Ben Philpott of KUT °µºÚ±¬ÁÏ reports on Morning Edition that Perry hopes to make a stand in the Palmetto State.

While GOP presidential candidate Mitt Romney savored his second consecutive win in the Republican nominating process, those who finished behind him in New Hampshire also continued on to South Carolina. They are hoping that it is in the Palmetto state where they can get his campaign to to stumble before it becomes unstoppable.

Fresh off his big wins in New Hampshire and Iowa, Republican presidential contender Mitt Romney took his campaign to South Carolina. That state votes a week from Saturday. The other Republicans are trying to throw up road blocks.

As the race heads to socially conservative South Carolina, the Republican presidential candidates are accusing each other of being less than pure on the issue.

Ever since 1980, the state's voters have correctly chosen the eventual Republican nominee, who has invariably been the candidate the party's establishment types have chosen to rally around. It's not for nothing that it's called the South Carolina Firewall.

After no-drama New Hampshire, the Palmetto State is shaping up to be a fierce battle for the Republican presidential nomination. It's also a crucial spot for opponents to derail Mitt Romney.

Even before his big win in New Hampshire, Mitt Romney was opening up a lead in South Carolina, the next state to host a GOP primary. It's possible support will solidify behind a challenger, but time is already running short.

Mitt Romney came away from the New Hampshire Republican presidential primary with a comfortable win, and an uncomfortable reality. His chief detractor, who has launched a savage campaign to undermine Romney's successful-businessman-makes-best-president narrative, is just getting warmed up.
