They will crisscross the state in planes, RVs and automobiles. They will be all over the radio and television. They might even call you at home.

Anything goes the last weekend before a big election.

The six Republicans running for the U.S. Senate have today, Sunday and Monday to make their final pushes before Tuesday’s primary election, when the field will get winnowed to no more than two.

And with former Gov. David Beasley — the clear front-runner in all campaign polls — almost assured of one spot in the June 22 runoff, the others are essentially vying for one lonely spot.

“We’re going to run around the state and turn out voters,” said Terry Sullivan, campaign manager for U.S. Rep. Jim DeMint’s Senate bid.

While Sullivan said they are “very comfortable about our position,” they are not taking chances. DeMint will be in Lexington, Aiken, Rock Hill and Cherokee County — and that’s just today.

“We’re hustling, because June 8 is very important, but June 22 is still in front of us,” Sullivan said.

Charleston businessman Thomas Ravenel would like nothing more than for DeMint to look ahead to the runoff.

Ravenel press secretary Mark Regalbuto said their polling shows Ravenel in a statistical dead heat with DeMint for second place. In their mind, Regalbuto said, it all comes down to who gets his supporters to the polls.

That is “critical to our success,” Regalbuto said.

While Ravenel will campaign up and down the coast this weekend, he has spent most of the past week in the Upstate, where he might be less well known, but where he believes he can win votes from native son DeMint.

Likewise, Sullivan said, their data shows DeMint is neck-and-neck with Ravenel in the Lowcountry.

And when it comes to the ground organizations that are critical to getting voters to the polls, DeMint is the acknowledged leader, if for no other reason than because he has been campaigning for the seat longer than the others.

Also in the mix for Tuesday is former Attorney General Charlie Condon of Charleston. Hehas his own RV and will be focusing this last weekend on playing up his national security credentials. Condon said his experience as attorney general gives him the most clout on security issues.

Condon’s “Stand Up for Freedom” tour began Friday and continues through Monday. Condon will visit military installations, fire departments, police headquarters and other places on the front lines of protection.

“We’ve got a theme here, and a message,” Condon said. “It’s not the idea of voter contact or rallying crowds, although we’re delighted to have supporters come by.”

Instead, he said, he is keeping the focus on what he calls the top issue in the campaign: national security.

Ravenel, too, is focusing on the war on terrorism and security. In an aggressive new radio ad running statewide, Ravenel says the United States should not allow terrorists to seek sanctuary in mosques. It also implies the Bush administration succumbed to “liberal” pressure in Washington when it ordered Marines to retreat from Fallujah in Iraq.

Ravenel is certainly not alone on the state’s radio and television airwaves. All four major candidates — Beasley, DeMint, Ravenel and Condon — as well as Myrtle Beach Mayor Mark McBride, are running television ads. Only Bluffton businesswoman Orly Benny Davis is not.

And while Beasley is the acknowledged front-runner, his campaign is taking nothing for granted. He will be in the Upstate, Midlands and Lowcountry today.

“We are working just as hard,” Beasley campaign manager Randy Page said. “We are working as if we’re 10 points down.”
