To avoid nasty quarrels with front-runner

Cleveland: Newt Gingrich, suddenly in danger of losing his perch as Mitt Romney's strongest GOP challenger, is fine-tuning his presidential campaign to place more emphasis on raising money, guarding his home turf and trying to avoid nasty quarrels with the front-runner.
Rick Santorum's stunning success in this week's elections in Colorado, Minnesota and Missouri has fuelled his claim that he, not Gingrich, is best qualified to rally conservatives who feel Romney is too moderate and unreliable.
Gingrich, the former House speaker, again faces a dilemma that has dogged him for much of the election. Should he show his feistier, meaner side at the risk of turning off voters who want pragmatic solutions more than expressions of anger? Or should he use a tamer, high-minded tone and risk losing economically anxious, resentful Republicans such as those who handed him his only victory, in South Carolina?
His aide RC Hammond said Gingrich favours the second option, for now.
"We need to go hard at demonstrating we are the one campaign of leadership," Hammond said in an interview in Cleveland, where Gingrich spoke on Wednesday without mentioning Santorum, Romney or his own poor showing in Tuesday's voting.
Gingrich wants to avoid the harsh personal exchanges with Romney that have sometimes dominated the Republican campaign, Hammond said, and he wants to show he's a better choice than Santorum by letting voters compare their records.
Eight fundraisers
Gingrich plans few public appearances in the coming week, and none in highly competitive states. He is to speak at a major convention of conservatives in Washington today. He plans to spend Monday to Wednesday in California, mixing a few public events with eight fundraisers, Hammond said.
On February 17 and 18, Gingrich will campaign in Georgia, the state he represented in Congress for 20 years ending in 1998.
