The 2005 Idol winner Underwood won 54 percent of the vote in an AOL Television poll, reports Contactmusic.
Kelly Clarkson, the first Idol winner in 2002, came in a distant second for most popular, pulling in only 26 percent of the vote from 1.3 million fans who took part.
Meanwhile, Simon Cowell wants his pals Telly duo Geordies Anthony McPartlin and Declan Donnelly, popularly known as Ant and Dec, to take over as hosts of his American Idol show.
The chances of McPartlin and Donnelly to join could come in the next two or three months when current show host Ryan Seacrest is expected to take over a top US talk show from veteran host Larry King.
