So you are taking what a blogger says he THINKS Cruz may do as evidence of what Cruz would actually do? Are you THAT gullible?
Why not take what Cruz has actually done in office as a guide to his future actions, as opposed to what someone thinks he will do based on their own opinions? While Cruz has engaged in some tactical legislating, Cruz has been the MOST consistent person in Congress in actually standing for the positions he promoted in his campaign. We don't know what Trump would do, because he has no record to judge.
To be fair, Cruz hasn't accomplished much of anything in the Senate as he is one of the few attempting to be responsible. I don't see any reason to believe, at this point, that he would be any more successful as the President.
If he is incapable of building a consensus in the Senate, why should we be confident that he could do any better in a higher office?
