U.S. Sen. Lindsey Graham may have a lot of competition when he seeks re-election next year, but he also has a lot of cash.

Graham’s campaign reported Thursday that he has raised more than $1.4 million for his re-election campaign since April, his best showing ever in a single quarter. His previous record for a fundraising quarter was $1.2 million.

All told, the donations bring Graham’s re-election war chest to more than $6.25 million, also a record for him.

“I feel like I’m running a good campaign,” Graham said Thursday. “I’ve raised the most money I’ve ever raised because people appreciate me trying to solve a problem like immigration.”

Graham was among a bipartisan group of eight senators that recently passed a major immigration reform bill.

Graham’s campaign manager, Scott Farmer, sounded a similar theme: “The country is facing some incredibly tough problems, and South Carolinians appreciate Senator Graham’s willingness to tackle these issues with common sense, conservative solutions,” he said.

Graham already faces one announced GOP primary opponent, Upstate businessman Richard Cash, who ran a close second to U.S. Rep. Jeff Duncan in the 2010 3rd Congressional District GOP runoff.

Even before this past quarter, Graham’s fundraising prowess had attracted note. Earlier this year, the Washington nonprofit Center for Public Integrity reported that Graham had raised more money from lobbyists ahead of the 2012 election than any other member of Congress save one — even though he wasn’t on the ballot that year.

About 10 percent of Graham’s $2.2 million haul, about $223,000, came from lobbyists acting as “bundlers,” a higher percentage than any other member, the center reported. Bundlers raise money from friends and associates and deliver the checks in a “bundle.”
