The onus is on Trump to unite the Republican Party and that includes the inescapable fact that Trump cannot win the White House if he loses Texas. Failing to secure the endorsement of a former governor/president as well as a sitting senator who clearly won the primary in Texas, puts that indispensable goal just a bit farther out of reach.

The onus is also on that former governor and president to be open to supporting a united party. Your post says that Trump is responsible, but doesn't reckon with the intransigence of the opposing factions.

In 2012, Romney had the task of unifying, explicitly with the imprimatur of the establishment, and he failed. He failed because the establishment has stopped listening to the voters.

Now, the voters have stood up to the establishment, and the establishment needs to be open to listening to the raised voices from across the party's spectrum. Trump is responsible for taking a reasonable line in trying to work with the party, but the party is also responsible for their own tantrums.

You're quite right, both sides have to mutually accommodate. However, in view of the despicable campaign conducted by Trump, in view of the fact that he is the one seeking the office in the general election, the onus remains on Trump to initiate the reconciliation.

There is no defense for what he did to Rafael Cruz or to the Cruise family in general and it requires Trump to begin the process of making amends to effect a reconciliation.

Trump cannot insult his way to victory in November.
