U.S. Sen. Lindsey Graham's campaign reported raising $873,178 during the first quarter of 2014, giving him more than $6.85 million cash-on-hand.

His six opponents in the June 10 Senate primary were less quick Tuesday to release their fundraising numbers, which have lagged well behind the incumbent to date.

Graham's re-election effort has now collected more than $11.6 million for the entire six-year election cycle.

"We're incredibly humbled by the thousands of South Carolinians who have supported Team Graham with their time and money," said campaign manager Scott Farmer.

"Senator Graham is traveling to every corner of the state meeting with voters, listening to their concerns about the tough issues facing our nation, and spreading his message of Ronald Reagan conservatism."

Tuesday was the cut-off for federal candidates to report their fundraising numbers covering the first three months of 2014.

Several of the other campaigns had not released their reports by late Tuesday. Columbia-area minister Det Bowers, released fundraising numbers last week showing he collected $417,367 for the period and leaving him with $384,250 cash on hand.

Berkeley County businesswoman Nancy Mace's campaign has raised $208,000 in this quarter with a total of $602,000 raised. It has $223,000 cash on hand. Upstate businessman Richard Cash has 464,056 cash on hand. Other candidates in the GOP Senate primary field include: state Sen. Lee Bright of Spartanburg; Orangeburg attorney Bill Connor; and newcomer Benjamin Dunn.

Graham's campaign recently has moved to blanket the state with ads, events and offices made possible by his large war chest. He has opened six regional campaign offices, including one in Charleston, and hosted events and released four television and radio ads.

A Winthrop Poll released two months ago found that Graham had a commanding lead in the primary but had not topped the 50 percent mark - which he will need on June 10 to avoid a June 24 runoff.

A new Winthrop Poll is scheduled to be released early Wednesday and is expected to update how Graham's popularity -and that of other South Carolina politicians - has changed in recent months.

In the last survey from February, Graham had the support of 45 percent of GOP voters, followed by Bright with 8.5 percent. The rest of the pack trailed with less than 4 percent each. Most of Graham's opponents have tried to tap into the tea party wing of the GOP.

Wednesday's new poll will be a survey of all state voters, unlike February's poll, which surveyed only likely GOP voters.

Democrats who filed for the seat include state Sen. Brad Hutto of Orangeburg, and Jay Stamper of the Columbia area.
