Newt Gingrich is riding high atop the latest poll in Iowa, but analysts say a closer look shows he may join Michele Bachmann, Rick Perry and Herman Cain as former frontrunners who went by the wayside.
Reuters reports that the University of Iowa poll has Gingrich with nearly 30% of the vote. Mitt Romney is second with his usual 20%.
The poll spanned a week that included Herman Cain eventually dropping out of the race. In the early part of the polling when Cain was still in the race, Gingrich was up at nearly 38%. After Cain left, Gingrich's support dropped to 24%.
"Our results show that his support may be starting to slide, as it has with previous frontrunners," said Frederick Boehmke, an associate professor of political science and an adviser to the poll.
Gingrich does not have an extensive operation in Iowa, and that could hurt him.
"Gingrich has spent little time (in Iowa)," Boehmke said. "While Gingrich is polling well, his minimal staff and grassroots organization in Iowa suggest he may be unable to turn out supporters on January 3 to the same degree as the others."
