While no Republican presidential candidate yet makes President Obama's team "shake in their shoes," Obama's campaign manager, David Plouffe tells the ABC 4 News that Utah Gov. Jon Huntsman (R) makes him, a "wee bit queasy... I think he's really out there speaking a lot of truth about the direction of the party."
Huntsman has been consulting with GOP strategist Frank Luntz, who himself is frustrated with the state of the Republican party today.
Interestingly, a recent KSL-TV/Deseret News poll found that Utah voters actually prefer Mitt Romney over Huntsman as their 2012 candidate by a 55% to 32% margin.
