A new poll from Texas firm IVR has Fred Thompson losing his position atop the Republican field in this Southern state — a further sign that his much-hyped campaign is falling flat.

Rudy Giuliani now tops the field with a small plurality of 24%, followed by Thompson at 19%, and Mike Huckabee and Mitt Romney tied with 14% each.

In August, Thompson led the GOP race in Texas with 29%.

The margin of error is ±4.3%.
