The pair have recently clashed over fundraising, with Graham’s team accusing the Democrat of trying to “buy a Senate seat” and Harrison hitting back at the Republican over donations from Super PACs. He went on to raise $2 million in 48 hours in donations to the “Lindsey Graham Retirement Fund.”

In a bid to give himself an edge, Graham has recently looked to use the confirmation of Amy Coney Barrett to her seat on the Supreme Court as a means to boost his campaign. Harrison on the other hand has said this situation could damage Graham when it comes to Election Day.

How Is The Race Shaping Up?

The race is rated as a toss-up by The Cook Political Report, with polling having tightened in the run up to the vote.

Recent polling from East Carolina University put Graham up by three points, with 49 percent of 763 likely voters asked October 24-25 saying they intend to back him, compared to 46 percent for Harrison. The poll has a margin of error of plus or minus 4.1 percent, meaning Graham’s lead fell within this.

A New York Times/Siena College poll which was put to 605 voters October 9 to 14 gave Graham a slightly wider lead but still in the single digits at six points. Of those asked, 46 percent said they would go for Graham over 40 percent for Harrison. The poll had a margin of error of plus or minus 4.5 percent.

However, previous polling has put the race tighter, with a CBS News/YouGov poll of 1,061 voters between September 22 and 25 putting Graham on 45 percent of support overall and his rival Harrison on 44 percent.

The poll’s margin of error was plus or minus 3.8 percent.

Harrison said in a recent tweet: “The people of South Carolina deserve a senator who will work on their behalf, not in his own self-interest.”

Graham has hit out at Harrison in a recent attack, suggesting the Democrat is trying to get voters to back a third party candidate who had dropped off the ballot in order to steer their votes away from him.

Newsweek has contacted Graham and Harrison for comment on the debate and the state of the race.
