RE: Cruz will lose in the general election. He is unable to connect with the average voter like Trump or to go across party lines.
THAT of course, remains to be seen. The latest polls show him LEADING Hillary Clinton and doing better against her than Trump.

So, I am not sure if your assertion is accurate at this point in time...
Trump will use every weapon at his disposal to win. Cruz, like McCain and Romney, like to portray themselves as being above the fray. They cannot utter the brutal tough language of the common man. Remember when Trump called Bergdhal a "dirty rotten traitor," who deserved to be shot? Trump has yet to train his guns on Hillary. I have no doubt that he has plenty of dirt on the Clintons based on his NY political connections. Trump will, like a Dem, fight to win at all costs. Forget decorum or the Marquess of Queensberry rules. It is war.
We are going to find out in about a month or so, if we still have a government of laws or not. The integrity of the FBI will be tested along with the DOJ. If the FBI recommends, as it should, that Hillary should be indicted, then Hillary is finished as a candidate even if the DOJ refuses to prosecute. If the FBI whitewashes the scandal, then we are witnessing the extent and depth of corruption in our system. It will be a sad day.
