People in IA would be delighted to nominate a Bush but not necessarily support him in November 2016.
The rest are Other/Undecided.
That puts the totals at 48 TEA, 34 GOPe, and 15 "other".
As long as we do not allow the MSM to divide the right-wing votes, the Conservative candidate should get the nomination. A Cruz/Walker ticket announced early on (would Walker take the VP "demotion" extra early?) should get past Paul, Carson, and Rubio. (All 3 should get solid cabinet position considerations... Carson on SCOTUS to replace Ginsberg, please.)
(And God help us all if we fail this Primary season.)
