I think Scott Walker may indeed be a dark horse for the Republican presidential nomination.
There will be a huge line-up of contenders, but Walker could come from behind to surprise us.
If Cruz gets in, everyone else can go home or get on Cruz control.
I think if Cruz get in Sarah Palin will take a pass since her priorities are the same as Cruz’. A Cruz-Palin ticket would result in a landslide win. Neither of them are afraid of going after Hillary.
