Answer, because the citizen who is not a member of their club got ahead in the election and is a perceived threat to the GOPe status quo.

I don't remember elections before where the party took such massive steps to block the election of their own party's candidate in order to force a brokered convention.
To such an extent they knowingly are giving the Presidency to Hillary.

What they are NOT realizing is that after years of betraying voters, the voters are no longer with them. They just burned their party down to the ground.

The Bushes, Cruz, the so called leadership is shooting the GOPe right in the head dead politically.

I don't see me after decades ever wanting to vote Republican again with the current turds in control of the party shenanigans.

“their own party’s candidate”

Until he gets to 1237, he isn’t the party’s candidate.

I dislike the RNC and GOPe far more than Hillary is disliked.
The efforts to which they are going to derail the front-running candidate is disgraceful.

If the GOPe steals the nomination from Trump their problems are just beginning. Trump will certainly run third party in 4 years and will have even more angry voters supporting him. Trump has worked really hard to win this and he's not going to just walk away.
