Incorrect. He attacked Cruz repeatedly starting in Iowa with lies of "lyin Ted" and all that other insulting nonsense. That was not politics as usual it was mean-spirited lying bullying. He's a bully and abominable in character as he's demonstrated time and time again.
No, voting your conscience is NOT a wasted vote. That nonsense starts with the assumption that my vote is the parties to begin with and I'm not doing my duty casting it for them. Wrong. That's not how this country was founded. The way it works is one candidate's must have more support than the other candidate. In choose Trump after it was evident he was (and is) unfit for the office, the GOP electorate decided to take their shot at Hillary with a proven weak candidate.
The problem is that more of the left who hate Hillary can hold their nose and vote for her. Those on the right like me with a moral conscience cannot do the same for Trump -- he's just that bad. Had we only had 4-5 candidates at the beginning, then Cruz would be the nominee and we'd be on the way to the White House... but nope... 17 in the race allowed Trump's minority of votes in most states to get him the nomination. They should correct that process so you have to get 50%+1 vote to win a state in the primary -- let the top two have a runoff three weeks later. But they (the GOP) didn't expect a knucklehead like Trump to be able to play the system and get the nomination until it was too late for the party and America.
So no, I will do as the Founding Fathers intended and vote FOR someone, not against another. The boogeyman of Hillary being setup is not enough for me to forsake my duty as a Christian and conservative and find a worthy candidate. If the rest of the GOP wants to jump off a cliff, I certainly don't have to follow.
And finally Cruz has betrayed his supporters. And you have nothing to base you claim of Trump being pro-life on. At all. His past record is 100% pro-choice. He's only pandering to get the vote of the right. If he truly changed and ran again in 8-12 years with a demonstrated change of heart and record, then fine, but for now his record and his current (not 11-year-old) behavior makes him unfit for the office of president and unworthy of my vote.
