Sen. Lindsey Graham, R-S.C., on Thursday pleaded for campaign donations on Fox News, as he faces a tight race against Democratic challenger Jaime Harrison.

Graham had entered the race as the clear favorite but Harrison has seen a surge in fundraising.

"My opponent will raise $100 million in the state of South Carolina,” Graham said. “The most money ever spent in the history of the state on a Senate race in this state was by me in 2014 when I spent $13 million.”

“I'm being killed financially. This money is because they hate my guts,” he continued.

Harrison has seen a sharp fundraising uptick after Supreme Court Justice Ruth Bader Ginsburg died on Friday. Harrison reportedly hauled in $6 million in the 72 hours after Ginsburg's death.

In the second quarter of the year, Harrison raised nearly $14 million, while Graham brought in $8.4 million. In the first quarter, Harrison brought in $7.4 million, while Graham raised a total of $5.6 million.

Graham, 65, has served as South Carolina’s senator since 2003 and was in the House of Representatives from 1995 to 2003. Once considered a moderate on issues such as climate change and immigration, Graham has become a staunch ally of President Donald Trump. Graham spoke out in favor of controversial Supreme Court nominee Brett Kavanaugh in 2018 and ardently defended Trump during his impeachment trial.

Harrison, 44, is an associate chairman of the Democratic National Committee and had served as the chair of the South Carolina Democratic Party from 2013 to 2017. Harrison has made his working-class background the center of his campaign and has attacked Graham for being out of touch with the state.

"Lindsey Graham, a man who I used to have tremendous respect for -- he's changed. He's not the same person," Harrison told the “Axios on HBO” program earlier this month. "I'm running against a guy who cares more about his own political relevance and his political power than he does addressing the issues that people are dealing with here on a day-to-day basis."

A recent Quinnipiac University poll shows Graham and Harrison tied in South Carolina, with each candidate receiving 48% of the vote. The Cook Political Report rates the race as “lean Republican.”

The Democrats will need either three or four seats to retake the Senate, depending on whether Democratic nominee Joe Biden wins the White House. Promising Senate races for Democrats include Arizona, Colorado, Maine, North Carolina, Georgia, Montana and Iowa.
