No he didn't.
What do you suppose he meant when he said "I have to stay true to my principles also. And I’m a conservative, but don’t forget, this is called the ‘Republican Party,’ not the ‘conservative party.’
As well as, "Does the party have to be together, does it have to be unified? I’m very different from anybody who’s perhaps ever run for office. I actually don’t think so. I think it would be better if it were unified, I think there would be something good about it, but I don’t actually think it has to be unified,”
Additionally, I would add in case there's any doubt, Trump not only has said he doesn't need conservatives, he shouted it from the mountains in his huge entitlement proposal regarding child care.
