Washington (CNN) -- We all know about the power of born-again and evangelical voters in the Iowa Republican presidential caucuses. Four years ago, three out of every five Iowans who attended a GOP precinct caucus described themselves that way, and they handed Baptist minister and former Arkansas Gov. Mike Huckabee an upset victory over former Massachusetts Gov. Mitt Romney. Minnesota Rep. Michele Bachmann, Texas Gov. Rick Perry and former Pennsylvania Sen. Rick Santorum would like to repeat that trick again on Tuesday. Whether 60% of the 2012 Iowa GOP caucus vote will be made up of self-described born-again or evangelical voters again, and whether any one of those candidates will be able to scoop up almost half of them as as Huckabee did, remains to be seen.

But their ability to consolidate power is questioned
"Bachmann and Perry are finished, they just don't know it yet," said one @placeholder insider dismissively.
