Santorum no less than Huckabee is a Bush-Rove faux candidate. I’m not sure why the emphasis on Huckabee.
In Iowa caucuses, Huckabee and Santorum were the main not-Mitt Romney candidates (McCain campaign looked dead in 2008 Iowa). Cruz certainly and Walker probably are the not-Jeb candidates now. No room for Huck and Rick.
Yes both Huck and Rick are being pushed/placed. The more not-Bushes the merrier for Bush-Rove-Clinton.
