The latest Associated Press-Ipsos poll found that nearly a quarter of Republicans are unwilling to back top-tier hopefuls Rudy Giuliani, Fred Thompson, John McCain or Mitt Romney, and no one candidate has emerged as the clear front-runner among Christian evangelicals.

Giuliani's popularity continued to decline steadily as he faced a spate of headline headaches, came under increased scrutiny and saw the potential entry of Thompson in the mix; his support is at 21 percent compared with 27 percent in June and 35 percent in March.
The former New York mayor is running virtually even with Thompson, who has become a threat without even officially entering the race.
