Why nominate him, then try to throw the election just to prove an outsider can't win? Why tarnish their own party that way? Wouldn't they rather have a candidate who could become president? Makes no sense.

Nah, I think what happened is they honestly thought they could coach him into acting like a president instead of how he acts. So they nominated him, and said 'ok Donny try not to be too obnoxious and alienate half the country'. And he decided he was superman and wasn't going to change his act for anyone, and went on to commit gaffe after gaffe after gaffe cause he just doesn't get it.

That's when the party started turning against him imo.
