Trump probably knew Cruz would not endorse him as evidenced by his supporters continued and pervasive antics to attack Trump prior to the convention.
Let's correct that.... Trump and his camp and the RNC ALREADY KNEW what Ted Cruz was going to say. His speech was given to them in advanced and pre-cleared. Trump himself said so.
Also, Cruz already told the Trump campaign that he was NOT going to give a tacit endorsement. Therefore, what Cruz was going to say is NOT a surprise to Trump. The surprise was ON CRUZ.
Regarding your other issue, Cruz' efforts to shut down government were a disaster. Instead of shutting down government, they should have passed proposed legislation repealing Obamacare and forcing Obama's veto and energy defending his actions.
Ha ha ha, pass legislation repealing Obamacare.... BEEN THERE DONE THAT. How many times have they passed legislation repealing Obamacare?
Bueller, Bueller, Anyone? Anyone?
READ HOW MANY TIMES HERE:

So, you are proposing that they do the same thing over and over again without achieving anything?
What does Congress have? They have the POWER OF THE PURSE, and that is what Cruz wanted them to use to stop Obamacare.
Did he get any support from the establishment Republicans? You know the answer. And for that he is hated....
