At some point this summer, Cruz and Trump will have to work together or they will both be defeated.
The part that most people DO NOT GET is that the Republican Party doesn’t care one iota if they lose to Hillary Clinton, their donors are still protected, and it is the donors that now control the Republican party. Most registered Republicans don’t GET that part of the equation. If Trump/Cruz does not win the nomination, and you stay home or even vote for Hillary, as a protest, they still win.
Pat Buchanan has some good advice for both the Cruz and Trump camps: “lock out the establishment“.
