Rove wants his guy to win.
Problem is, officially, he's not working for anybody.
Maybe so but I think is Jack the ripper gets the nomination Karl Rove will decide he’s a nice enough guy and back him.
I think one of the most instructive lessons in politics is the marriage of Mary Matlin and James Carville ....I think they do believe in their respective points of view but only so far.....so such a marriage is possible .
Karl Rove will certainly stand against a wind to a pont. ....then if the wind blows hard enough off he will go in that direction ....in short If Caine survives and prospers Rove will fully back him.
