South Carolina Tuesday news roundup

COLUMBIA, South Carolina (CNN) - Here's a quick look at what's making political news in South Carolina this Tuesday morning:

In Rock Hill Monday night, former president Bill Clinton defended his wife from charges that she is "unelectable."

Check out this quote from Rep. Bob Inglis, on Mitt Romney: "I told him, you cannot equate Mormonism with Christianity; you cannot say, 'I am a Christian just like you ... If he does that, every Baptist preacher in the South is going to have to go to the pulpit on Sunday and explain the differences." More here on how evangelicals are telling Romney not to equate Mormonism with Christianity.

The Clinton and Obama campaigns will both file papers to be official candidates on the South Carolina primary ballot today. Both campaigns will organize supporters this afternoon at the headquarters of the South Carolina Democratic Party in Columbia.

The John Edwards campaign was first to file - they lined up outside the Democratic Party headquarters door at 7 a.m. on Oct. 22 to file papers.

Several campaigns announced yesterday they will campaign in South Carolina later this week and this weekend. That's on top of President Bush's visit to Columbia on Friday, when he will fundraise for Sen. Lindsey Graham's re-election bid.

Sen. John McCain will bring his hard-working campaign back to South Carolina for the third time this month starting on Thursday. He will campaign for three days in Myrtle Beach, Goose Creek, North Charleston, Lexington, Irmo and finally up in Simpsonville.

Edwards will return to his birth state to make a two-day campaign swing starting Friday in Cheraw, Lancaster and Rock Hill. On Saturday he will host a fundraising breakfast in Columbia for state Rep. Bill Clyburn, who has endorsed Edwards.

Also on Friday, Obama will hold a "community gathering" at the Clarendon County Courthouse in Manning, the site of Briggs v. Elliot, one of the four historic Brown v. Board cases. (Edwards made Briggs v. Elliot the centerpiece of a campaign visit to South Carolina two weeks ago.)

Sen. Joe Biden will campaign in the Upstate on Friday and Saturday. He will visit Gaffney, Greenville and Anderson. On Saturday, Biden will march in the Greenville HBCU Classic Parade and attend the HBCU football game in the evening.
