Came across this great article today.

To give a summary of the best part:
Robert Botsch, a University of South Carolina-Aiken professor, said if Graham has a problem it's likely to be in the GOP primary with its hard-core conservative base.
The general election is safe for Graham, Botsch maintains. "He is the closest thing we've had to a Democratic senator in a long time," Botsch noted.
Even Democrats agree.
Last year, Joe Erwin of Greenville, immediate past chairman of the S.C. Democratic Party, was asked what Democrat might challenge Graham in 2008. Erwin doubted anyone would.
"We already have our best Democrat up there in Lindsey," Erwin quipped.
What makes this really incredible is when you consider that Fritz Hollings, one of the most liberal Democrats in the senate, just retired as a SC senator in 2004. Lindsey just need to make it official and flip his letter after his name from a R to a D.
