A candidate with vision for the US!

HIS supporters make thousands of campaign calls and blanket Florida with signs as they dream of Newt Gingrich in the White House, but for many in his Republican Party such a scenario would be nothing short of a nightmare.

After the former House speaker's shock win in South Carolina, morale soared at Newt headquarters in this sprawling city four days ahead of a crucial Florida primary that could put Gingrich — or his main rival Mitt Romney — in the driver's seat as they chase the Republican presidential nomination.

Dozens of volunteers swarmed the ground oor of a small red brick house as they carried out campaign duties for the most controversial conservative in the race to see who will go head to head with President Barack Obama in November.

"We went from 50 volunteers to about 250," said Gingrich's local campaign chairman Bert Ralston.

They put up campaign placards, distribute "Newt 2012" stickers, strategise, and of course make calls to prospective voters seeking their support for a candidate whose rivals deride him as bombastic and "erratic."

The calls are simple and direct, with volunteers reading from a script. An 11-year-old boy made some 75 campaign calls for Gingrich, volunteer John Libby said.

Retired history professor Don Rawlins, energised by the ultra-conservative Tea Party movement, is a fervent Gingrich supporter who helped post Newt signs at a campaign rally on the University of North Florida campus.

"The country is under water, the house is ooded, and we want the best plumber, regardless of the aws he may have," Rawlins said.

Gingrich has been castigated by social conservatives for his extramarital affairs that led to two messy divorces, and his toxic reign as House speaker in the 1990s has received fresh scrutiny.

Recently, conservative pundits have been among his most ardent critics, saying that while Romney might be too moderate to be a true conservative, the former Massachusetts governor and millionaire investor would be a stronger candidate against Obama.

But Rawlins said he is looking beyond Gingrich's shortcomings and occasional pie-in-the-sky ideas, including claims he will establish a permanent moon base by 2020 if elected.

"He is straightforward, he discusses the things that matter, he has the experience," Rawlins said.

Leaette Vollmar, who travelled 900 km from Tennessee with her niece to attend the Gingrich rally at the University of North Florida, was equally succinct.

"He is bright, he knows how to get the job done, he won't ip op," she said.

"He (Romney) is from Massachusetts, that tells it all," Vollmar said of the historically liberal state.

In Florida Gingrich has often compared himself to conservative icon Ronald Reagan, the 1980s Republican president. He has hoped to capitalise on an electorate frustrated by high unemployment and a collapsed housing market, and who he hopes recognises the anti-establishment bent to his campaign speeches.

But after a bump, Gingrich is suffering a post-carolina slump, with a new poll last Friday showing Romney has opened up a nine-point lead among likely Republican voters in Florida.
