If Trump’s ground game is to destroy the integrity of the Republican party, then yes, I do not like that.
Seems to include challenging the integrity of some aspects of the Republican party. As to destroying this integrity, let us consider a thought experiment. What if the Republican party magically and suddenly conceded to all his challenges. It seems to me the results would be that:
* Republican politicians would no longer do favors for big campaign donors.
* Delegate slots won by a candidate would always be filled by delegates loyal to that candidate, and never assigned by the candidate's political enemies.
* Republican primaries and caucuses would be organized in a way conducive to broad participation by Republicans in the state.
* If at the convention a candidate has a significant lead, but only a plurality that is close to a majority, and polling indicates they would have had a majority in a two candidate race, then delegates who are unbound should come together to support the leading candidate in the interest of party unity and respect to the voters.
Albeit, these things would be favorable to Trump in the current election cycle. Perhaps he could challenge other things not as favorable to him. But putting the particulars of this election cycle aside, by themselves it seems to me that they would strengthen the integrity of the Republican party and certainly would not destroy it.
You’re on the wrong side of the issue.
