I don't think he will be in the general election so the point is moot.
The Party will have to bite the bullet and deny him the nomination as un-electable.
At that point, we will find out if Condi's declaration is due to Trump, or is more of the Sherman-esque variety.
The party will not ditch him, and deny him the nomination simply because he passed the 1237 mark

, how are they going to steal it from him??
How is he unelectable when he beat 13 other people running against him

, and had about roughly 13 Million + votes in the primaries..
If they deny, him his supporters will burn down Cleveland, I don't think the party wants to go down that road.
Who will they put in his place, Hillary will kill Cruz, Rubio, or Kasich Or anyone they wanna stick in his place..
I'm not voting for the asshole, but it's a little late in the game for substitution.
